反辐射导弹抗海上机动目标关机仿真研究

Research on the Simulation of Anti Radiation Missile Anti Marine Maneuvering Target Shutdown

研究反辐射导弹对海上机动航行舰艇雷达的抗关机能力。在分析目标机动规避范围的基础上推出概率密度函数,依据船舶操纵方程建立了目标随机转弯机动模型。根据反辐射导弹制导误差分布规律建立了其末端随机弹道方程。给出了符合目标特性的命中判读条件,并采用蒙特卡洛法进行了仿真。仿真结果客观反映了关机距离和弹道入射角等因素对命中概率的影响,为反舰型反辐射导弹可行性研究和效能评估提供有益参考。

In order to study the anti shutdown capability of ARM to marine maneuvering ship radar the probability density function was pro- posed based on the analysis of target maneuvering circumvention range, and the random turning maneuvering model of the target was built according to the ship handling equation. The terminal stochastic ballistic equation of ARM was established according to the distribution law of ARM guidance. The hit interpretation condition corresponding to target properties was given, and the simulation was carried out by Monte Carlo method. The simulation results objectively reflected the effect of switching-off distance and trajectory incident angle on hit probability, which provided useful references for feasibility research and effectiveness evaluation of anti-ship ARM.
