Jamming Research to SAR based on Frequency Characteristic

摘要

This work is concerned with developing the blanket jamming technology against SAR based on frequency characteristic. Firstly, the SAR imaging output of the shift frequency jamming style is deduced and analyzed. Then a modified shift frequency jamming to SAR, random Shift frequency jamming (RSFJ), is presented and discussed. The theoretic research and simulation show that the RSFJ is an effective blanket jamming style to SAR with the less jamming power requirement than noise jamming.
