A research team led by Professor Jiang Weixiang from Southeast University in Nanjing published the weapon’s design concept, key algorithms and manufacturing methods in a peer-reviewed paper published in the November issue of the Journal of the University of Electronic Science and Technology of China. .
In such a battle, some less developed countries could lose control of the electromagnetic spectrum before losing territory.
“Losing control of the electromagnetic spectrum will inevitably lead to losing control of the air and sea,” Jiang and his colleagues wrote in their paper.
“To adapt to a high-conflict environment, electronic countermeasures systems must be multi-functional, multi-target countermeasures, and have broadband capabilities.”
Most electronic warfare equipment currently in use is only capable of high-power, sustained suppression of targets in more or less the same direction. Notable examples include electronic warfare pods deployed on U.S. F-15 and F-16 or Russian MiG-27 and MiG-29 fighter jets.
Only a handful of countries have acquired the new generation of electronic warfare weapons technology, with Israeli Aerospace Industries leading the way with the Scorpius-SP pod. This compact device is about the same size as an air-to-air missile and can be mounted under the wing of a fighter jet. The company says it can identify and simultaneously suppress targets in multiple directions, including fighter jets, ground radar, and even incoming missiles. This ability protects friendly fighters from harm.
Images of the prototype released by Jiang’s team show that the technological approach taken by Chinese scientists appears to be distinctly different from Israel’s. For example, Israeli antennas are constructed from a number of sharp cones, whereas Israeli antennas feature a honeycomb-like open-ended waveguide structure.
Modern electronic warfare systems rely on transmitting and receiving antennas made up of many individual units, each controlled by a computer.
In theory, these units could engage individual targets, but in real-world applications, antennas are often divided into small segments that emit electromagnetic waves with limited power and narrow frequency ranges. Masu.
This approach, commonly referred to as multi-target digital array technology, has been primarily limited to radars with moderate power and bandwidth requirements.
But Jiang’s team has discovered that a structurally simple antenna array made of cost-effective components can operate at maximum capacity, while at the same time sophisticatedly manipulating the electromagnetic waves emitted by each antenna to direct them in different directions. They claim to have developed a new control method that can suppress multiple targets. unit.

Furthermore, the frequency of suppression can be adjusted for each target. However, there are trade-offs. The amount and complexity of numerical processing information increases exponentially with the number of targets and can overwhelm military computer chips.
Nevertheless, the researchers published an algorithm in their study that significantly reduced the computational load, paving the way for the technology to be widely adopted worldwide.
According to data on Southeast University’s website, 414 graduates from the Class of 2022 joined Huawei, more than any other company.
Earlier this year, Huawei recognized 23 Southeast University teachers who helped solve critical technical problems, more than any other university in China.

Jiang’s team did not elaborate on why they chose to publish the technology in their paper, but the researchers highlighted its “broad application prospects” in radar, communications and electronic countermeasures.
The Chinese government said it was not involved in the dissemination of these technologies.
