Abstract

Abstract: To overcome the problem low probability of detection of pulse radar under strong Radio Frequency (RF) noise interference, a radio frequency noise interference suppression technique is proposed based on estimation-feedback integration. Firstly, pretreatment of the blind source separation is performed for the echo signal. The parameters of the target echo signal are estimated according to the characteristics of FRactional Fourier Transform (FRFT), and the narrowband filter is used to filter out most of the interference and noise energy. Then, using the M/N logic method to perform the trace processing in the data layer, and combining the radial velocity direction, detection of target track prediction is realized. Finally, using the data layer of track state feedback real-time correction filter parameters, the interference energy is better filtered out in the signal layer and the interrupt track is also filtered out to complete RF jamming suppression. The simulation results show that the algorithm proposed has better interference suppression effect compared with existing RF noise interference suppression techniques.

Key words: FRactional Fourier Transform (FRFT), narrowband filtering, estimated detection, feedback regulation, integrated processing
