China seems to be planning to use electronic attacks designed to damage or control U.S. drones. There are reports that China is attempting to interfere with U.S. drones. In recent years, the United States has at least once been willing to use drone jammers to prevent aircraft from taking off from the United States. The United States carries out surveillance missions in the Nansha Islands.
Murmansk-BN is the world’s most powerful long-range electronic warfare (EW) system developed by KRET, a subsidiary of Rostec Holding. The EW system is designed to disrupt radio communications within a maximum range of more than 3,000 kilometers (1,864 miles). The jammer is specially designed to solve high-frequency communication systems (including global high-frequency communication systems).
Some jammers launched at the beginning of the war, such as GPS jammers in vehicles, reported later updates aimed at overcoming various threat signals. Ryan explained that, for example, the in-vehicle gps interference radiation currently present in thousands of cars in theaters represents a technological capacity increase.
Electronic warfare jammers need to analyze a wide bandwidth with low signal-to-noise ratio (SNR) to detect critical and time-sensitive threats. One way to achieve this is to channelize a wide bandwidth through a filter bank and fast Fourier transform (FFT) to separate the signal of interest from noise and interference sources.
