Abstract:

Hyperbolic frequency modulated (HFM) is a waveform with the characteristic of Doppler invariance, and it has a high application value in the wideband radar imaging of high-speed targets. Interrupted-sampling repeater jamming (ISRJ), as a common type of radar jamming, can cause multiple false targets jamming by using coherent characteristics of pulse compression radar, which greatly limits the detection of radar with linear frequency modulated waveform. Firstly, the correlation is derived between the effect of ISRJ and the parameters of HFM waveforms based on the model analysis of HFM waveform and ISRJ. Then, the analysis shows that the HFM waveform can not only have the characteristic of Doppler invariance, but also have the effective jamming suppression performance caused by ISRJ compared with linear frequency modulated waveform. The conclusion provides a theoretical basis for the anti-jamming design of HFM waveform, and the numerical simulations verify the effectiveness of the conclusion.

Key words: hyperbolic frequency modulated (HFM) waveform, interrupted sampling repeater jamming (ISRJ), anti-jamming, waveform design
