Compared with an air borne SAR, a missile borne SAR has three important characteristics including high flight speed, straight movement with non constant velocity and big squint angle, which bring forward a greater requirement for the real time performance, precision of motion compensation and azimuth resolution of the imaging algorithm. In this paper, in light of the imaging characteristics of missile borne MMW spotlight SAR for a ground target, some main problems including the imaging resolution and selection of pulse repetition frequency are discussed. Then a new scheme of motion compensation which consists of range alignment, phase adjustment and compensation for the movement with non constant velocity is presented. Image reconstruction algorithm by using super resolution spectrum estimation is given based on linear spectrum extrapolation technique. Finally the simulation results prove the validity of the algorithm.
