China Electronics Technology Group Corp, one of the world's largest suppliers of defense electronics, is promoting a new-generation radar system that can counter almost all types of air threats in modern warfare.

The YLC-16 multifunctional S-band radar system incorporates an all-digital, full-solid active phased array, advanced chips and other state-of-the-art technologies and is capable of detecting and tracking stealth aircraft, helicopters, drones, cruise missiles and loitering munitions, said Tang Ji, a manager at the CETC 14th Institute in Nanjing, Jiangsu province.

The Nanjing institute is the country's largest and strongest developer of military radar. Its products have been sold to dozens of nations.

"It is one of the latest radar models CETC is offering on the international market and is the best three-dimensional, middle-range surveillance radar any buyer now can find on the market. Many foreign militaries, like some in Africa and Asia, have expressed strong interest in this radar system and proposed to come to our institute to see the real product and learn more about it," he said at the 10th World Radio Detection and Ranging Expo, which kicked off on Thursday in Beijing.

Thanks to the use of cutting-edge technologies and modular designs, the YLC-16 features a streamlined appearance, low power consumption and a very high level of operational stability and reliability, Tang said.

These advantages will enable users to field the radar in regions with tough conditions such as high mountains, uninhabitable islands and plateaus, and controllers can remotely operate the equipment without staying on-site, the manager said, noting that data can be transmitted back in a real-time manner via optical fiber, microwave or satellite.

He added the radar's antennas and their covers are foldable and can open and close within only several minutes.

In addition to its military functions, the radar can also work in the civil aviation sector to monitor air traffic, according to him.

Besides the surveillance radar system, Tang's institute has developed and is testing what it calls the world's most advanced meteorological radar.

The GLC-36S active phased array radar is capable of carrying out multi-dimensional precision scanning of hazardous weather including typhoons, rainstorms and thunderstorms to help researchers capture data about the meteorological phenomena's complex inner structure.

Information obtained by the radar will improve studies of the rapid formation of meteorological hazards, thus effectively boost the capability of monitoring and forecasting extreme weather, Tang said, adding the product started field testing in Fujian province in December 2021.

Beijing's leading provider of defense electronics, China Electronics Technology Group Corp., is promoting its new-generation radar system that can allegedly fend off almost all air threats in modern combat.

The YLC-16 multipurpose S-band radar system uses cutting-edge technologies such as an all-digital, fully solid active phased array, sophisticated processors, and other cutting-edge components, according to a report by state-affiliated China Daily on Saturday.

"It is one of the latest radar models CETC is offering on the international market and is the best three-dimensional, middle-range surveillance radar any buyer now can find on the market," said Tang Ji, a manager at the CETC during the 10th World Radio Detection and Ranging Expo in Beijing.

"Many foreign militaries, like some in Africa and Asia, have expressed strong interest in this radar system and proposed to come to our institute to see the real product and learn more about it,"

This system is claimed to be capable of spotting and tracking cruise missiles, drones, helicopters, stealth aircraft, and loitering weapons. Foreign militaries in Asia and Africa have shown interest in knowing more about the product after drawing attention to it.

The YLC-16 is the top three-dimensional, middle-range surveillance radar system on the market, said Tang Ji, a manager at Nanjing's CETC 14th Institute.

The radar is sleek-looking, uses little power, and operates with a high degree of stability and dependability. The modular structure also enables remote control and real-time data transmission by optical fiber, microwave, or satellite.

Foldable antennas and covers on the radar make for easy opening and closing in a matter of minutes.

Multipurpose radar system​

The YLC-16 can perform non-military tasks like monitoring air traffic in the civil aviation industry. The GLC-36S active phased array radar, which enables multi-dimensional precise scanning of hazardous weather, was also developed by CETC 14th Institute.

In order to get information on the intricate inner structure of the weather phenomenon, this also covers typhoons, rainstorms, and thunderstorms.

The radar's information will increase our ability to track and predict extreme weather, reducing the effect of natural disasters.

China's largest and most influential producer of military radar is Tang's Institute. The new YLC-16 radar system is the most recent offering on the global market, and the items have already been sold to numerous countries.

The product began field testing in the province of Fujian in December 2021 and is anticipated to draw in more potential customers.

For purchasers looking for sophisticated and dependable surveillance radar systems, the YLC-16 is a great investment because of its cutting-edge technologies and flexible designs.

Because of its modular construction, which enables remote operation, it can be used in challenging environments such as steep mountains, uninhabited islands, and plateaus.

The ability to transmit real-time data by optical fiber, microwave, or satellite enables prompt and effective reactions, noted the China Daily news article.

China is building the most powerful warship radar on record: scientists​

published : 7 Jun 2023 at 10:39

Chinese scientists have revealed that construction has begun of a radar system that could shift the balance of naval power in the world's oceans with its ability to detect incoming missiles from thousands of kilometres away.

A Chinese military vessel equipped with the radar would be able to detect a ballistic missile from up to 4,500km (2,800 miles) away - about the distance from southern China to northern Australia, according to scientists involved in the project.

The radar can also track multiple targets within 3,500km, or about the distance to Guam, the researchers said, in a peer-reviewed paper published on May 31 by the Chinese-language journal Electric Machines and Control.

The team of scientists and engineers, led by associate professor Sun Donyang from the Harbin University of Science and Technology, said the radar is suitable for installation on new Chinese warships, with the first system already in construction.

While the line of sight can be affected by the Earth's curve, the unprecedented boost in search and tracking capabilities could give the PLA Navy a major advantage, the researchers said.

Radars in most military vessels have a working range of a few hundred kilometres, limited by the immense power required to extend their capability. The researchers said they overcame the problem, making the system suitable for newer ships with electric propulsion systems.

According to the paper, the new-generation active phased array radar is made up of "tens of thousands" of transceivers, an order of magnitude far greater than featured in more usual devices, the researchers said.

Each transceiving array unit can send and receive signals as an independent radar. When working together, these units can generate pulse electromagnetic signals as powerful as 30 megawatts - enough to wreck the electrics of any warship in existence.

A Beijing-based radar scientist who was not involved in the project said that until recently the idea of putting a 30 megawatt radar on a battleship was "more or less science fiction".

But China is under enormous pressure to develop better radars for its warships because of the increasing US military activities in Asia, said the scientist, who asked not to be named due to the issue's sensitivity.

"The more powerful our naval radar becomes, the more likely it is that we can suppress the US in the South China Sea."

Size can be a problem when developing long-range radar systems. For instance, Florida's 32-megawatt AN/FPS-85 radar - the world's most powerful, according to its owner the US Space Force - takes up more than 23,000 square metres (250,000 sq ft) of floor space, or three soccer fields.

Technological advances have significantly reduced the size of high-power radars, with some critical components available in larger quantities and at lower prices than ever before, thanks to the mass application of 5G technology.

But the power supply for their groundbreaking radar remained a challenge for Sun and his colleagues, who had to overcome the radar's tendency to produce extremely strong electric shocks when generating its powerful signals in rapid pulses.

To prevent damage to the other electronic devices within the confined space of a vessel, Sun's team had to separate the radar from the ship's power network. This would require some large, high-performance capacitors to act as a buffer, they said.

The researchers turned to high-speed train manufacturer China Railway Rolling Stock Corporation (CRRC), the world's largest maker of bullet trains that built the world's first mass production line for super capacitors in 2013.

High-speed trains in China are driven by high-voltage current to reach an operational speed of up to 350km/h (217mph), with powerful and reliable capacitors ensuring a smooth and stable energy supply over long distances.

Sun's team said test results suggested that customised capacitors made by CRRC for the radar could almost eliminate the power shocks it generates. And at slightly over 1 tonne, the entire power supply system with capacitors and other components is small enough to fit in a ship, they said.

It is also surprisingly efficient, according to the researchers. Even at full capacity, the radar would only impose a constant load of 235 kilowatts on the ship's power supply network, which could be handled by the generators on mainstream warships, they said.

Electromagnetic radiation is also a major concern when developing large-scale radar systems. It remains unclear from the paper what effect the device could have on the sailors on board or marine life.

The radar's development is unusual, in that cutting-edge technology is more commonly applied first in the defence industry before trickling down to civilian manufacturing sectors.

"It can also work the other way around, especially when we need to produce a large number of advanced weapons at a low cost," the Beijing-based radar researcher said.

China has built more than 40,000km of high-speed railways - enough to circle the Earth - in less than 15 years, providing the industrial expertise that Sun's team were able to draw on for their project.

The researchers were also able to take advantage of China's embrace of 5G. By the end of last year, the country's telecommunication companies had deployed 2.3 million base stations nationwide - significantly ahead of the US, which has about 175,000, according to some industry estimates.

China also dwarfs the US in shipbuilding capability, with 13 naval shipyards producing some of the world's largest and most advanced warships.

US Navy Secretary Carlos Del Toro said in February that one of these shipyards has more capacity than all of the United States' seven facilities combined. "That presents a real threat," he said.
