The basic principle of synthetic aperture radar (SAR) interference confrontation is discussed, and a SAR interference countermeasure simulation system is developed. The simulation system can perform functional level SAR signal reconnaissance and simulation to simulate SAR imaging and detection under various clutter and interference backgrounds And identify the process, and can interfere with a variety of interference patterns to assess the effectiveness of the interference and the actual scenario warfare optimization. The functional principle of each module of the simulation system is introduced in detail, and the simulation examples are given to demonstrate.
