空舰反辐射导弹激光引信光学系统及光束配置研究

Airfoil Anti-radiation Missile Laser Fuze Optical System and Beam Configuration

针对空舰反辐射导弹攻击舰载雷达目标增配激光引信的需求,论文首先对激光引信光学系统中收发系统设计、激光发射器选取以及采用组合透镜进行光束整形,以达到压缩发散角的目的。然后通过建立探测概率模型分析了激光引信最大探测概率及最优光束配置情况,最后提出了一种提高探测概率的双探测平面光束优化设计。通过Matlab仿真分析,结果表明导弹俯仰角越小、雷达天线越高,引信探测概率越大而与弹体的探测倾角无关,同时在理论上验证了双探测平面光束优化设计的探测概率比原先单探测平面高。

In order to meet the demand of airship anti-radiation missiles to attack shipborne radar targets with the addition oflaser fuses,this paper firstly designs the transceiver system in the laser fuse optical system,the selection of laser emitters,and thebeam shaping using a combination lens to achieve the purpose of compressing the launch angle. Then the detection probability modelis used to analyze the maximum detection probability of the laser fuze and the optimal beam configuration. Finally,a dual detectionplane beam optimization design is proposed to improve the detection probability. Through Matlab simulation analysis,the resultsshow that the smaller the pitch angle of the missile is and the higher the radar antenna is, the higher the detection probability of thefuse and the detection inclination of the missile are. The theoretical probability is that the detection probability of the double probeplane beam optimization design is better than the original one.
