Research on Optimization of Suppression Interference Cancellation Algorithm

Radar anti-jamming technology is an important part of the radar signal system. Its principle is to suppress the influence of interference on the function of the radar signal system by identifying and estimating the radar interference and using anti-interference algorithms to deal with different interference types. As a kind of interference commonly used in radar, suppression interference has a great influence on the target echo characteristics of the radar signal system. Therefore, studying the suppression interference cancellation algorithm has great theoretical and practical significance. In this paper, the author takes the noise FM interference of radar suppression interference as the research object, and expounds the radar interference and radar anti-interference technology. After analyzing the principle of suppression interference cancellation algorithm based on interference reconstruction and simulation, an optimization algorithm is proposed. The simulation results show that the proposed optimization algorithm can reduce the energy loss of target echos and improve the amplitude of pulse compression results, which can improve the performance of radar signal system subsequent processing.
