摘要
末制导技术的应用是提高导弹打击精度的有效途径.针对弹道导弹再入段弹道的特点,将合成孔径雷达(SAR)传感器应用到弹道导弹末制导中,应用卡尔曼滤波技术,将SAR获得的导航信息与惯导信息进行融合,用以提高导弹再入段的自主性和射击精度.仿真结果表明,SINS/SAR组合系统能够较大地提高导弹的射击精度.
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.
