反辐射导弹对水面舰艇作战末端弹道分析

Terminal Trajectory Analysis of Anti-Radiation Missile Towards the Warship

针对反辐射导弹对水面舰艇的作战问题,基于比例导引规律,建立了反辐射导弹末端弹道模型并进行了仿真分析。考虑到实际中反辐射导弹控制电路的延迟以及最大过载的限制,对比例导引规律进行了修正。以水面舰艇的搜索雷达为攻击目标,研究了低数据率条件下反辐射导弹的末端弹道轨迹以及末端弹道的需用过载。仿真结果表明,测角噪声、控制电路的延迟和低数据率导致了反辐射导弹脱靶量的增大。最后以蒙特卡罗实验,分析了脱靶距离的数值以及测角噪声、控制电路的延迟和低数据率对脱靶量的影响程度。

Based on the proportional guidance law, a terminal ballistic model of anti-radiation missile is established and some simulations are conducted. Given the control circuit delays and limitation of the maximum overload, the proportional guidance law is modified. Considering the warship to be the target, the terminal ballistic trajectory as well as the overload is studied. The simulation results show that, meas- urement noise, the control circuit delay and low data rate lead to the increase the miss distance. Finally, the Monte Carlo experiments are used to analyze the degree of miss distance influence by measurement noise, the control circuit delay and low data rate.
