Synthetic aperture radar(SAR)has significant application value in both military and civilian,due to its excellent resolution imaging ability and good adaption to various time and weather.In the military field,SAR is widely used to discover various strategic targets,such as tanks,troops,patrol boats,deployment of enemy weapon system and other important strategic materials.In the civilian field,SAR is used for topographic mapping,preventing various weath-er phenomena such as hail,floods,droughts,hurricanes and so on.The continuous progress of SAR technology has brought great challenges to the defense of important military targets.How to interfere with SAR and reduce its detection and recognition performance on military targets,so as to guarantee that these targets can carry out military tasks safely and efficiently,is still an urgent problem to be solved.This paper expounds the development status of SAR jamming technology,analyzes the challenges and difficulties of SAR jamming technology at the current stage,and looks forward to its development trend,in order to provide useful reference for researchers in related fields.
