末制导雷达搜索模型的建立是反舰导弹捕捉概率计算过程中重点研究的问题。在分析了反舰导弹末制导雷达搜索过程特点的基础上,将末制导雷达的搜索过程细化为扫描波束的运动过程,分为随着导弹一起的平移运动和扫描波束自身的转动,建立了末制导雷达动态搜索过程的数学模型。以捕鲸叉导弹的末制导雷达搜索过程为例,对所建模型进行了仿真验证。

Search model of terminal guidance radar of anti-ship missile is very important for probability calculation of target acquisi-tion of anti-ship missile. On the basis of analyzing the search characters of terminal guidance radar of anti-ship missile, the search process of the terminal guidance radar was reduced to the movement of scan beam. The movement included the translational move-ment following the missile body's movement and the rotational movement of scan beam, the mathematic model of the terminal guidance radar dynamic search was built up. The search process of the terminal guidance radar of Harpoon missile was analyzed, the mathematic model in this paper was simulated and validated.
