摘　　要：深入研究了反舰导弹末制导雷达目标捕捉模型,以末制导雷达第一方位搜索周期捕捉概率和全程搜索捕捉概率为约束条件,建立了以末制导雷达第一方位搜索周期扫描面积为目标函数的末制导雷达最优搜索图求取模型,解决了基于目标距离的末制导雷达最优搜索图参数求取问题,并利用多项式拟合,得到了最优搜索图参数工程实现方法,该方法易编程、计算量小、占用内存少,是一种简单、实用的中远程反舰导弹末制导雷达最优搜索图参数实现方法。This article presents a comprehensive study of the acquisition model of an anti-ship missile homing radar.To meet the constraints of acquisition-probabilities of the first animus-search period and the global search of the homing radar,an objective function is built on the scan-area of the homing radar in the first animus-search period,which is used to calculate the optimum search-graph of the homing radar,thus achieving the optimum search-graph of the homing radar varying with the target distance.Furthermore,a polynomial-fitting model is built on the calculated optimum data of the search-graph,which is easily programmed,required small storage space and less computational complexity for the actual fire control system.The conclusion is that it is a simple and practical method in calculating the optimum search-graph of the homing radar of long or medium range anti-ship missiles.
