Open publisher page 1 citations

Abstract

The terminal guidance technology is an effective way to improve the missile attacking accuracy.According to the trajectory characteristics of ballistic missile at reentry stage,the technology of Synthetic Aperture Radar(SAR) sensors was employed in the terminal guidance.The SAR information and inertial navigation information were fused by Kalman filter technology.The autonomy and attacking accuracy of the missile can be increased at reentry stage.The results of simulation show that SINS/SAR integrated navigation system can improve attacking accuracy greatly.
