A Design of Motion Compensation for High Resolution Imaging of Missile-Borne SAR
The accurate motion compensation is important for gaining high resolution of imaging for some characteristics of missile-borne SAR, such as high speed, motion pose errors, high real-time and so on. The paper first introduces the two types of errors of missile-borne SAR and their effects to image. Subsequently, the first class of error, including normal face error and error along flight route, is described in details due to its serious effects to imaging. At the same time, the corresponding compensation algorithms are also showed. Finally, the paper gives the simulation results that the phase compensation to Doppler phase errors resulting from slant distance can improve the imaging resolution effectively. In the meantime, the phase compensation to Doppler modulation frequency errors resulting from speed error ameliorates Doppler mismatching. The resolution of the system reaches two meter.
