摘　　要：受常规弹药空间和系统功耗的限制,激光近炸引信应用于常规弹药过程中,无法布置多个激光器和多个激光接收器,同时,系统结构要求尽量简单,故传统的光束布局方式无法直接应用;现设计出一种新型的单光束大视场脉冲旋转周向扫描方案,建立了弹目交会模型并进行了目标捕获率理论分析,讨论了系统误差的影响因素,加工制作了初始原理样机并进行了高速风洞实验,结果表明:该方案能够在转速80 000 r/min以下实现可靠联接,及常规弹药激光近炸引信360°大视场周向探测,在保证弹目交会目标捕获率的前提下,可有效减小常规弹药引信空间的占用率和系统功耗。Due to space and system power limitation of fuze, when laser proximity fuze is used in conventional ammunition, multiple lasers and multiple laser receivers can＇t be laid out. Meanwhile, system architecture is required to be as simple as possible. Therefore, the traditional layout of the beam can＇t be directly applied. A new rotation circumferential scanning program of large field of single-beam, was designed. Missile target encounter model was established and theoretical analysis on target acquisition rate was conducted. System error factors were discussed. The initial prototype was processed and high-speed wind tunnel experiment was done. The results show that the program can achieve reliable connection when the speed is less then 80 000 r/min, 360° large field of detection of laser proximity fuze used in conventional ammunition can be realized. Under the premise of ensuring target acquisition rate, fuze space utilization of conventional munitions and system power can be effectively reduced.
