1results about How to "Achieving Interference Suppression" patented technology

The existing time-frequency domain false target jamming suppression method generally requires high jamming parameter estimation accuracy, and the application scene is relatively limited. Therefore, the present application provides a DRFM jamming suppression method based on the spike distribution characteristics after pulse compression. The algorithm does not require prior information of jamming parameters, analyzes and summarizes the spike distribution characteristics after DRFM jamming pulse compression, counts the number of spike intervals according to the spike distribution characteristics, designs a corresponding decision threshold, thereby distinguishes the target and the jamming, and realizes the jamming suppression on this basis. The present application can suppress the false target jamming in a complex electromagnetic environment, and has a low calculation degree, and can improve the anti-jamming capability of the radar.
