空地反辐射导弹对抗雷达关机全弹道仿真研究

THE STUDY ABOUT THE ALL-TRAJECTORY SIMULATION OF THE ANTAGONISM AGAINST THE RADAR STOPPING RADIATING OF AN ANTIRADIATION MISSILE

对抗雷达关机是反辐射导弹一项重大关键技术。本文采用了被动雷达寻的复合惯性末制导做为反辐射导弹的抗雷达关机方案；通过卡尔曼滤波方法解决了惯性基准轴误差修正问题；最后结合导弹运动方程组对导弹从发射点开始至雷达关机点，直到导弹落地的飞行全过程进行了全弹道仿真。仿真结果说明了抗雷达关机方案的有效性。

The antagonism against the radar stopping radiating is a key technology of the antiradiation missile. In this paper,the passive radar homing combined with the strap down inertial guidance is used on an antiradiation missile to work against the radar stopping radiating. The direction error of the inertial axis is corrected by using the Kalman filter. At last, in terms of a set of motion equations,the all-trajectory simulation of the flight prosess of the missile is carried out from the launch point to that of radar stopping radiating, then to that of the missile hitting the ground. The results demonstrate the effectiveness of the method.
