Synthetic aperture radar(SAR)has the advantages like high resolution, all-weather and so on. It is considered to be a powerful tool to improve guidance accuracy of precision gaided weapon. Guidance precision was an important per-formance measurement of precision-guided weapons. The main factors affect the accuracy of SAR guidance system are scene matching errors, real-time imaging acquisition and pretreatment errors, inertial measurement errors, navigation guid-ance errors caused by the SAR guidance trajectory. The studies on SAR guidance accuracy of the influencing factors were described. The research and the conclusions were comparied and analized. The existing problems in the research and de-velopment direction were pointed out.
