摘　　要：为提高远程弹道导弹的命中精度,针对其纵向误差明显高于横向误差的特点,提出一种运用单基站的测距系统,精确测量发射点至弹体的距离,并融合惯导的导航信息对径向速度进行精确估计的复合制导方法,以提高导弹的纵向精度。这种方法对地面布站无特殊要求,基站可安装在发射车上随车机动。仿真结果表明,该方法能将导弹的射程偏差减小至纯惯性制导时代三分之一。A compound guidance method based on INS and one dimension distance measured by terrestrial system is presented in this paper. For long-range ballistic missile, the downrange’s error is bigger than the crossrange’s error, and there is one velocity which determines the downrange’s error. This paper integrates INS and accurate distance measured by terrestrial system to receive a more precise velocity, which can improve the point of fall accuracy at last. This scheme has no especially request to lay the terrestrial system’s station, and is effective and efficient to enhance anti-interference ability. The result of simulation shows that this method can obtain a decrease of 2/3 in the downrange’s error.
