The report regards SLC-7 as a champion radar with all-round capabilities. SLC-7 adopts a solid active digital phase array system able to ditect and track multiple targets and capable of resisting saturation attacks. It has various advantages including long range, high ratio of data, self-adapting resistance to jamming, high speed in identifying target, high reliability and the capability of simultaneous search, identification, capture and track of multiple targets.

The radar can be regarded as a top multipurpose radar with more applications than many other similar radars. It can deal with not only stealth aircrafts, conventional fixed win airplanes, helicopters, drones, cruise missiles, tactic missiles, near space targets, etc. but also position targets of artillery and rocket artillery.

It is prominent for its super anti-jamming capability.

This is a UHF waveband three dimentional early waring radat with an antenna as big as a badminton court. Such an antenna gives it extreme high identification capability and great power and indicates its superb engineering achievement and technology. The radar, in addition, adoptes sophisticated information processing technology to ensure detection of the most advanced stealth fighter jets.

In addition to strong anti-stealth capability, the radar has lots of other characteristics such as the ability to detect various kinds of targets at long distance with high identification capability, strong anti-jamming capabiltiy, etc. Its major functions are better than similar types of radar abroad.

YLC-8E radar can provide comprehensive intelligence and information for combat command system, interception weapons system and air force. It has relatively strong capabilities of synthesizing intelligence and providing independent guidance.

China’s Brilliant Radars Displayed in Recent Nanjing Expo (1)


Quite a few most advanced Chinese radars are recently displayed In the 9th World Radar Expo at Nanjing, China from April 22 to 24, including KLJ-7A fire control radar carried by fighter jet, SLC-2E artillery nemesis, SLC-7 three-dimensional early warning radar, YLC-8E anti-stealth early warning radar, YLC-18 low altitude defense radar, YLC-48 portable multi-functional reconnaissance radar nicknamed drone terminator, etc.

Among them, KLJ-7A is China’s first active phase array fire control radar for fighter jet to be marketed in world market. It is characterized by high degree of freedom, broad band-width and strong anti-jamming capability. It can easily generate various wave shapes to deal with different kinds of target, can, in addition, simultaneously counter source of interference at various directions. It is as good as similar top products in the world in view of its entire technology.

Its speed of overall response has been greatly raised due to the use of optical fiber for data transmission so that its capability to monitor far-away targets is twice better than traditional radar.

KLJ-7A radar can track and guide missiles to hit quite a few targets at the same time. It has thus laid sound foundation for fighter jets to find and hit targets earlier.

SLC-2E radar is an S-band weapon position radar using entirely solid active phase array system, highly reliable, adaptable to environment and mobile and able to operate 24-hour in whatever weather. It can detect the position of not only mortars but also heavy artillery and rocket artillery with changing high-speed trajectory. In addition, it can detect the position of armed helicopters to better satisfy artillery’s operational needs.

SLC-2E radar’s operational speed is very high. It adopts the technology of fully automatic operation, able to switch between marching and fighting modes in 5 minutes. As it uses advanced algorithm, high-speed procession module, it is able to realize the guiding for our fire counterattack when enemy’s shells are still flying in the air.

SLC-2 series of radar have long been exported due to their fine performance and is now one of the only three similar products of high performance on world market.

China’s New Anti-Stealth Radars Can Detect, Track & Shoot US’ F-22 & F-35 Fighter Jets – Military Experts


Published 11 hours ago on November 20, 2020By Smriti Chaudhary

With the US Air Force boasting stealthy fighters like Lockheed Martin’s F-22 Raptors and the F-35 Lightning II, China has claimed to have developed a meter wave anti-stealth radar that can detect advanced stealth. Moreover, the radar is capable of guiding missiles towards stealthy fighter jets.

“Meter wave radar can be deployed on vehicles, on land and warships, creating a dense web that gives hostile stealth aircraft nowhere to hide,” Chinese military experts told the Global Times, a tabloid under the auspices of the Chinese Communist Party.

It added that the modern stealth aircraft are designed to avoid detection by microwave radar, and are less stealthy to meter wave radar. Earlier, experts believed that meter wave radars could only send warnings about incoming threats because of their low resolution and accuracy.

However, Chinese military expert, Wu Jianqi, a senior scientist at the state-owned China Electronics Technology Group Corporation (CETC) who conducted researches and designed anti-stealth radar, with his team, has found a solution.

Dave Majumdar of National Interest explained the problem with High Frequency (HF) radar. According to him, while HF radar can detect and even track stealth aircraft to a degree, it is not anywhere near precise enough to guide a weapon. “The problem with HF-band radars is that they have a very long pulse width and a very low pulse repetition frequency [PRF].

That means HF are very poor at accurately determining range, altitude and precise direction. Indeed the radar resolution cells could be several miles wide.” He added that the radar can only cue other sensors to search the airspace or direct fighters toward a roughly defined search area.

“Wu solved the issue by designing the world’s first practical meter wave sparse array synthetic impulse and aperture radar,” according to Global Times. “Wu said that his radar has multiple transmitting and receiving antennas tens of meters high, scattered in a range of tens to hundreds of meters. They can continuously cover the sky as the radar receives echoes from all directions.”

According to Chinese military expert, Wei Dongxu, this will help the radar to hunt an aerial target, give the stealth fighter jets’ exact coordinates “by synthesizing parameters and data gathered by the radar under the support of advanced algorithms.”

“Since the radar can now see stealth aircraft clearly and track them continuously and accurately, it could become capable of guiding long-range anti-aircraft missiles and landing precision strikes on them,” Wei told the Chinese tabloid.

Meanwhile, China isn’t the first country to boast of the anti-stealth radar. In 2018, Russia revealed P-18-2 (an evolved version of Soviet-era P-18), surveillance and targeting radar, capable of detecting targets that use stealth technology.

P-18-2 radar is highly mobile and is able to receive additional (flight) information from airborne transponders using the integrated secondary radars. Rosoboronexport, the sole state intermediary agency for Russia’s exports/imports defense-related products, touted it as a Very High Frequency (VHF) radar with azimuth coverage upto 360 degrees.

It can be used for “detection, tracking, coordinates measurement (distance and azimuth), and state attribution of various flying objects in demanding active and passive jamming environment, active noise jammer direction finding,” it said.

Wu noted that while other countries are also developing such radars, he is confident that Chinese ones are “the best”. “As for now, I do not see a meter wave air defense radar from abroad that can match the criteria of the advanced meter wave radar [like the one China has],” he concluded.

Chinese Radar Can Detect, Track, Guide Hitting F-22, B-21, etc.


In National Interest’s article “Not Good: China Claims It Can Find and Track the F-22” by Michael Peck on October 8, 2019, the author says that the physics Chinese experts claim about Chinese radar’s capabilities to detect, track and guide long-range missiles to shoot down F-22 and other stealth warplanes “seem plausible”. That means he cannot deny the claim. He, however, has to ask: “How easily can the Chinese meter-wave radar be spoofed or jammed? How vulnerable are these radar complexes – comprising multiple antennae – to being destroyed by missiles?”

That is practical. Since China has such powerful radar, what the US can do is but to spoof, jam or destroy the radar by missiles. He does not know whether and how the US can do that as he has no answers to his questions!

Venezuelan Air Defence’s Chinese-made Radar Detects US F-22 Stealth Jet


Our Bureau 09:16 AM, May 13, 2020 10442

A Chinese-made type JY-27 radar deployed by Venezuelan Air Defense detected a United States F22 stealth aircraft as it approached the country’s airspace and sent a warning to the American fighter jet on Tuesday.

According to Avia Pro website, following the incident the Venezuelan army issued a warning to the US Air Force on May 12 that it was ready to fire without warning at any American aircraft if it tried to violate the country’s airspace.

The F-22 had attempted to violate the country’s borders in a “provocative manner,” information released by the site said quoting unnamed military sources.

The website said that the radar that detected the top-of-the-line American fighter is a Chinese-made radar type JY-27.

The incident follows the May 6 failed invasion attempt when mercenaries hired by a US security contractor were intercepted before they could carry out a mission to assassinate Venezuelan President Nicholas Maduro. Two US citizens, part of the invading party, have been arrested.

The Chinese made type JY-27 ‘Wide Mat’ long-range early warning radar is claimed to detect stealth aircraft up to 500 km radius. In February 2016, the radar tracked an F-22 which was on its way to South Korea from Japan, Chinese media has claimed. However other reports say the tracking may have been facilitated by external fuel tanks on the F-22 needed to undertake the long trip.

China had revealed the radar at the 2016 Zhuhai air show. Called the JY-27A 3-D, it is a Very High Frequency (VHF) active phased array radar. VHF radars, with their longer wavelengths are capable of detecting stealth aircraft.

The radar is said to have been sold to several countries including Venezuela and Pakistan. If the Venezuelan detection of the F-22 is proven, then it is bad news for the US military which has developed the F-22 and F-35 on the assumption that enemy radars will not be able to detect these aircraft until it is too late to avoid an attack.

The radar is mounted on a mobile platform which enables it to move away after detecting the enemy aircraft, thus avoiding counter-measures.

Editorial comment: Venezuela had ordered up to 9 JYL-1 long range 3D air surveillance radars from China starting 2006. However, there is no information of it having acquired the more modern JY-27 3D radar. Nevertheless, China is known to deploy its cutting edge defence equipment for tests with friendly countries.

The theory of the placement of the JY-27 radar with friendly countries for testing gains currency following the detection of one such radar in a Pakistani air base in August 2019. Pakistan has not announced the purchase; nor did China reveal the sale without identifying the customer, as it normally does.

China had cliamed a major breakthrough in radar technology with the development of JY-27 very high frequency (VHF) radar specifically marking out the F-22 and F-35 fighter jets as within its gaze. It may want to test the radar extensively in regions where there is considerable movement of US aircraft.

Development of Hypersonic Warplanes Ends Era of Stealth


China has developed radar able to detect and track stealth warplanes so that it can guide long-range missiles to shoot down US stealth warplanes.

The panic aroused by such invention causes National Interest to republish its September-2019 article “China Claims It Can Detect Stealth Planes Like the F-22 Raptor: Do you believe them?” to ease the panic.

The article cannot deny the possibility that F-22 may be detected and tracked by China’s new advanced radar so that it says, “the physics of the Chinese claims seem plausible.”

However, it asks,”How easily can the Chinese meter-wave radar be spoofed or jammed? How vulnerable are these radar complexes – comprising multiple antennae – to being destroyed by missiles?”

Now, it is not the question of whether China’s radar can detect, track and guide missile to shoot down US stealth warplanes but how the radar can be blocked or destroyed. It is a question of the capabilities of electronic warfare instead of the capabilities of China’s radar to detect and track stealth warplanes.

China will certainly be able to develop technology to prevent its radar from being spoofed or jammed and air defense to protect its radar.

Helpless, the article could not but conclude by saying “But stealth – or anti-stealth – will only be proven in a conflict”.

It is, however, a undeniable fact that no existing weapons are able to intercept a hypersonic warplane.

Knowing stealth will be vulnerable to new radar, China is now making great efforts to develop hypersonic warplanes that US radar can detect but no US weapons can intercept..

Pentagon knows that well but it lacks funds to develop hypersonic warplanes and the weapons to intercept them. China, however, has lots of funds to do so.

China says it can track F-35s operating in stealth mode with new radar


By News Desk –

2019-08-07

China has developed a meter wave anti-stealth radar it says can be used to spot enemy stealth aircraft and even guide Chinese missiles toward them, China’s Global Times has reported.

Speaking to the newspaper, Wu Jiangqi, a senior defence scientist at China Electronics Technology Group, a state-owned electronics giant which creates of a variety of applications for civilian and military use, including radars, said that meter wave radar “can fulfill the requirement” of detecting enemy stealth systems with high precision “as long as they are designed to serve this purpose.”

The new radar, which can be deployed across a range of platforms, from vehicles to warships, as well as stationary installations, is said to be designed to hone in on stealth aircraft, which are designed to be ‘invisible’ to microwave radar, by using meter wave radar.

Wu’s team is said to have solved the fundamental problem of low resolution and accuracy of meter wave systems by creating a ‘meter wave sparse array synthetic impulse and aperture radar’, which monitors the skies consistently, processing pings from an array of transmitting and receiving antennas reaching dozens of meters into the air.

According to Wu, his team’s anti-stealth radar is unmatched in its capabilities. “As for now, I do not see a meter wave air defence radar from abroad that can match the criteria of the advanced meter wave radar [like the one China has],” he said.

Commenting on the report, National Interest, a prominent US publication specialising in defence issues, said questions remain regarding the effectiveness of the new Chinese anti-stealth radar system, noting that Chinese engineers have not specified how susceptibility to jamming or spoofing, along with its potential vulnerability to enemy missiles is dealt with.

In the end, the problem with evaluating anti-stealth is the same as evaluating stealth: we really won’t know how well any of this will work until it is used in combat,” contributor Michael Peck wrote.

Russian defence analysts have long said that Russia’s Podsolnukh (‘Sunflower’) radar is already capable of detecting and tracking the F-35 and other stealth aircraft, with the system having a reported ability to detect objects at sea and in the air at a distance of about 500 km, in the line of sight or over the horizon.

As of 2016, three Podsolnukh stations were in operation along Russia’s maritime borders: one in the Sea of Okhotsk, one in the Sea of Japan and one in the Caspian Sea, with the defence ministry reportedly planning to build and deploy more. An export version of the Podsolnukh has also been showcased at several international expos dedicated to maritime defence technology.

Chinese new radar system immune to radar killer missiles


June 2019 News Navy Naval Maritime Defense Industry Posted On Thursday, 13 June 2019 15:54

The China’s maritime early warning system appears to be immune to “radar killer” missiles and is reported to be capable of detecting stealth aircraft, according to its development team led by Chinese academician Liu Yongtan.

The maritime radar system, developed by a team led by Chinese academician Liu Yongtan, can detect naval and aerial hostiles hundreds of kilometres away under any weather condition according to an interview given by the developer to Chinese media. It features high-frequency electromagnetic waves that have long wavelengths and wide beams, Liu said in an interview with the Naval and Merchant Ships magazine published this month.

While electromagnetic waves emitted by a normal radar travel in straight lines and, since the Earth is round, cannot help see what is beyond the horizon, the high-frequency ones used by Liu’s radar travel along the sea surface, and he said this makes it possible to detect and monitor vessels and aircraft beyond visual range.

The long wavelengths used by the system mean it could also detect stealth aircraft, Liu said. This is because current stealth aircraft are mainly designed to hide from microwaves and not waves of longer wavelengths, experts said. The radar can also avoid attacks from anti-radiation missiles, thanks to the waves’ wide beams because such missiles cannot carry antenna large enough (to track them), Liu said.

A land-based version of the system can detect naval and aerial hostiles hundreds of kilometres away, which helps expand China’s maritime early warning and defence depth, Liu said. Variants of the system can also be equipped on ships, providing them with early warning capabilities in the high seas with a much farther detection range, he said.
