摘　　要：制导工具系统误差对飞行器落点精度影响重大,其造成的落点偏差占总落点偏差的70%以上。根据飞行器飞行力学模型,利用计算机仿真技术实现对真实打靶的模拟,研究在显式制导下,制导工具系统误差对飞行器落点精度的影响。算例结果表明,蒙特卡洛方法可以给出在一定制导工具系统误差系数方差下,飞行器的圆概率落点偏差。The systematic errors of guidance instruments play a vital role in the accuracy of space-craft fall points, and the errors of the fall points influenced by guidance instruments is up to 70 % of the total fall points errors. Based on the flight mechanics model of spacecraft,the computer simulation tech-nology is used to simulate the real shooting target,and the accuracy of spacecraft of fall points influenced by guidance instruments errors are studied in the explicit guidance conditions. The simulation shows that the circular probable errors of spacecraft fall points could be obtained under a certain variance of the sys-tematic error coefficient of guidance instruments by using the Monte Carlo method.
