【Abstract】

Bistatic radar is gaining more and more interest by the radar community over the last years,and Micro-Doppler information is regarded to be the unique features of radar's targets.In this paper,a geometric of bistatic radar and vibrating target is constructed.Then in bistatic radar system,the Micro-Doppler information reduced by vibrating structure of target is analysis via Gabor-Transform.Then we get that vibrating parts and the relationship between target and radar will modulate the micro-Doppler frequency.Lastly the simulation results validate the conclusions.
