Abstract:

In complex electromagnetic scenes, many kinds of repeater jamming exist at the same time, which affects the detection of radar seriously. Nevertheless, traditional waveform design methods mostly focus on one kind of specific jamming, and the effect is limited in the face of multiple repeater jamming. To solve this problem, comprehensive optimization design of waveform is proposed, which combines linear frequency modulated along with phase coded intra pulse and frequency agile modulated inter pulse. Firstly, based on the analysis of multiple intra and inter pulse repeater jamming patterns, the cost function is designed considering the characteristics of both jamming and waveform. Then, the genetic annealing simulated algorithm (GASA) is used to optimize waveform parameters in order to have good jamming suppression effect. Finally, simulation experiments verify the effectiveness of the proposed waveform.

Key words: interrupted sampling repeater jamming (ISRJ), dense repeater jamming, genetic annealing simulated algorithm (GASA), waveform design
