舰载雷达系统包含的舰载雷达数量多、类型不一而且分布密集,在反辐射导弹(ARM)反舰作战时,对不同类型的捕捉能力决定了ARM的制导和命中精度。根据舰载雷达的工作方式、辐射信号空间分布特点和ARM导引头信号分选机理,建立了ARM对舰载雷达系统的攻击模型,该模型可用于求解ARM对不同舰艇各型舰载雷达的捕捉概率。仿真结果表明,在采用随机工作方式下,ARM难以捕捉发射功率相对小、但波束稳定的制导雷达,而对搜索周期短、发射功率大的舰载搜索雷达有较高的捕捉概率。

The ship-borne radar system is composed of various radars which are densely distributed. The acquisition ability of ARM to various types of ship-borne radar target determines guidance and hit accuracy error of ARM. Based on working modes of ARM, the distribution characteristic of radiation signals and signal sorting principles of ARM, attacking models of ARM to ship-borne radar system were built, which can be used to calculate acquisition probability of ARM to various types of ship-borne radar. The simulation results show that if ARM adopts random working mode, it's easier to acquire searching radar with larger transmit power and smaller search cycle, but hard to acquire the guidance radar.
