Study on anti-jamming frequency selection in radar netting

Radar anti-jamming, a struggle of radar for electromagnetic spectrum against the jamming equipment, nowadays has been a key factor influencing the overall situation of a modern war. As a radar anti-jamming technology, frequency selection suppresses jamming by taking advantage of the difference between the frequency domain feature of the radar signal and that of the jamming signal. However, most of the studies on the technology are more theoretical than practical. This paper studies the frequency selection technology for anti-jamming in radar netting, focusing on the possibility of avoiding jamming and the frequency bands to be avoided, and thus providing scientific and theoretical foundation for electronic warfare, decision support and radar control. The algorithm proposed features high operational speed and easy implementation, and simulation results have proved its effectiveness.
