摘　　要：为避免反辐射导弹近炸引信因开机过早而出现早炸、误炸的情况,提出了一种利用被动雷达导引头测得的目标视线角速度给出近炸引信开机信号的方法.给出了利用导引头测角信息计算目标视线角速度的方法,建立了末段弹道上目标视线角速度与弹目距离的统计关系;分别以近炸引信不过晚开机和不过早开机为原则,得到了引信开机时导弹到靶平面距离概率分布函数的上下界.仿真结果表明：在不能直接命中目标天线的情况下,引信开机时导弹到靶平面的距离主要集中在30-120m,在可以直接命中目标天线的情况下,引信开机时导弹到靶平面的距离小于30m.To avoid the faulty burst of anti-radiation missile （ARM） caused by proximity fuze early starting, a method was put forward, which could choose the starting position of the proximity fuze with the target sight line angular speed information from passive radar seeker, and could calculate the target sight line angular speed with angular information. The statistic relationship between target sight line speed and the missile-target distance was set up. According to the principles of start before the latest position and start as late as possible, the upper and lower limits of missile-target distance PDF were discussed respectively when the proximity fuze started. The simulation results show that： if ARM could not hit the target antenna directly, proximity fuze would start at the position with 30--120 m to the target plane; if ARM could hit the target antenna directly, proximity fuze would start at the position with less than 30 m to the target plane.
