Abstract :
DBS (Doppler beam sharpening) technique is widely used in military. In this paper, the basic theory of DBS imaging is introduced at first, and a conclusion is reached by analysis that range cell migration correction technique and azimuth dechirping technique can improve image quality effectively on SAR/GMTI (synthetic aperture radar/ground moving target indication) mode. And it is possible to form the moving target trajectory on the image because of the high resolution. Lastly, some satisfactory results based on the raw radar data are presented
