Abstract:

The jamming to SAR(Synthetic Aperture Radar) is an important and difficult issue to electronic warfare.This paper analyzes the works of jamming to SAR by rebound mode.Range compress and Cross-range compress is discussed in detail,and effect of jamming is got by the analysis.A method of raw data creation and data compression is used to simulate the jamming effectiveness.By Matlab simulation,the analysis results verify that the method affect the SAR image and can cover up the protected area.

Key words: SAR;jamming;range compress;doppler frequency
