Design of SAR Jamming Signal Generating System

This paper introduces several basic types of SAR jamming signals and provides a jamming signal generating system scheme.This scheme retains all merits of SAR echo signals in the circumstance of zero-IF,which has practical significance for SAR coherence and deceive jamming.Outfield tests validate the validity of this system.Based on the command and information from the reconnaissance system,the system can produce appropriate jamming signals in realtime,such as coherence,noise,etc.The system can easily be reused,expanded and flexible.The software-hardware design based on DSP has good reference value to the jamming signal generation for other radars and the design of radar echo simulator.
