Research on Anti-range False Target Jamming Technique based on Quasi KLT Basis

Interrupted sampling pulse repeating jamming is a new type of range deception jamming, which can produce deceptive and suppressive jamming effects on chirp radars. In addition, the jammer has the ability to instantaneously forward such jamming, so that the traditional waveform diversity technology cannot achieve the suppression of such range deception jamming. Therefore, this paper proposes a dictionary learning method based on the quasi-KLT base, which can realize the separation of the target and the jamming signal, and finally achieve the purpose of suppressing the jamming. The results of simulation experiments show that the proposed method can effectively combat the interrupted sampling and repeating range false target jamming.
