This paper takes one low-speed-circumgyrate rocket with a empennage asa research object, set up a relevant reference frame, analyse the strength andmoment on the amended rocket, ratiocinate the sports equation with 6 DOF; analyse the factors which cause terminal windage between pratical trajectoryand fiducial trajectory, take certain rocket for example, make use of theemluator on the influence of estimating precision caused by measuredinformation, find the speed, the trajectory obliquity, the trajectory setoverand the coordinate are the sensitive factor arosing terminal windage of thetrajectory; introduce the developing status of detecting technique, and basedon the actuality, choose the radar in the ground as measure equipment; simplydesign and analyse the setting and inflame control of the impulse engine onthe amended rocket; design the amend method and validate its feasibility takingthe use of emluator.

本文以某型低速旋转尾翼火箭弹为研究对象，建立了相应的坐标系，详细的分析了作用在弹道修正弹上的力和力矩，由动量定理和动量矩定理推导出了在一般形式下的弹道修正弹的空间六自由度的运动方程；对引起弹道落点偏差的因素进行了分析，以某口径火箭弹为例仿真了可测信息量对估算精度的影响，发现速度大小、弹道倾角、弹道偏角和位置坐标是引起落点偏差的主要因素；对弹道探测技术发展现状作综合性阐述，并基于现状，选用地面火控雷达作为测量装置；对弹道修正弹上脉冲推力器的安装和点火控制方法进行了简要的设计与分析；设计了弹道修正弹指令修正的修正方法，通过数字仿真验证了方法的可行性。
