Abstract :
This work is concerned with developing the frequency-based jamming technology against SAR. Firstly, the shift frequency jamming to LFM radar and SAR is analyzed. Then a modified shift frequency jamming to SAR, stepped shift frequency jamming (SSFJ), is presented and discussed. The theoretic research and simulation show that the SSFJ is inter/intra partly coherent with the SAR system and has a region imaging output for protecting the distributed targets. Its jamming power is much less than other jamming styles such as noise jamming, random shift frequency jamming and etc.
