Details of this innovative technology were published in a peer-reviewed paper in the Chinese journal Radio Communications Technology by project lead scientist Yang Kai, a professor at the School of Information and Electronics at Beijing Institute of Technology, and his team. . January 17th.
Yang wrote in his paper that the new breed of electromagnetic spectrum monitoring equipment is “small, high-performance, and low-power.”
This technology was previously considered a pipe dream due to the huge amount of data that needs to be processed during combat.
Scientists said this would cause “major changes in warfare technology”.

China and the United States are currently embroiled in a bitter battle over control of the electromagnetic spectrum.
While there may be elements of exaggeration in Chinese propaganda, the officers and soldiers interviewed revealed an important detail: They activated electromagnetic emitters, including high-power phased array radar, and were able to use the US military in attacks. It closely tracked a series of targets, including carrier-based aircraft. and electronic warfare defense.
According to Yang, due to hardware limitations, the real-time analysis bandwidth of traditional spectrum monitoring systems is generally limited to the range of 40 to 160 MHz.
Signals outside this range, especially high frequency signals, are typically monitored by sampling scans. This method increases the chance of missing something important.
This means that even if the U.S. military suddenly switches to a civilian frequency and sends out a pulsed signal for a short period of time, the Chinese military can pick it up and analyze it. As a result, radio communications between U.S. military units could be affected or disrupted by China’s crackdown.
To achieve this broader functionality, the scientists said they developed a series of new signal processing chips.

When all these signals are captured by high-performance antennas, a large amount of data flow is generated. Previous digital processing chips could not handle such huge workloads.
But Yang said the new chip can effectively split this large amount of data into smaller streams before processing the calculations. This reduces the processing load and allows a large number of signal sources to be monitored simultaneously over a wide frequency range.
The scientists also improved the structure of the electromagnetic signal filter that works with the chip and used new mathematical techniques to improve the processor’s efficiency without sacrificing signal.
Surveillance devices must also perform automatic analysis of processed signals to obtain valuable information such as the signal’s physical parameters, modulation method, and identification of friendly or civilian sources. Traditional methods cannot provide reliable analysis quickly.
The integration of homegrown chips and AI enables the Chinese military to achieve unprecedented intelligence and perception capabilities at low cost. Even in the face of enemy interference, powerful background noise allows us to detect enemy weaknesses and counter them effectively, Yang’s team wrote in their paper.

He was also very active internationally, working at Bell Laboratories and participating in the development of several international telecommunications standards. He currently serves as Executive Director of the Green Communications and Computing Technology Committee of the IEEE, the world’s largest organization of electronics engineers.
Some scientists attribute the rapid development of China’s military electromagnetic technology to its world-leading communications industry.
China’s leading telecommunications companies, such as Huawei, have invested heavily in cutting-edge wireless communications technology and reaped significant profits.
