A Study on Active Jamming &O Synthetic Aperture

Synthetic aperture radar (SAR) has its own special features different from conventional radar. It has high processing gain, so jamming to SAR is more difficult than that to conventional radar. Jamming to SAR finds its important usage in some military scene. Started with the operating features of the SAR, the possibility and the effectiveness of several active jamming methods to SAR are analyzed. Because of high processing gain for SAR, it needs very high barrage power to jamming SAR, and it is a good method to adopt deceptive jamming. The simulated results of generating deceptive signal are presented in this paper. It was founded that the jamming method of barrage plus deception is an effective one.
