针对水下弹目交汇时引信需在近程(大于10 m)获取目标的距离和方位信息,为充分利用发射激光能量,增大激光回波功率,对水下单光束脉冲激光方位识别系统角度参数进行了优化设计。通过推导水下脉冲激光方位识别系统探测目标的回波功率方程,建立了回波功率与系统角度参数之间的关系,得出水下脉冲激光方位识别系统角度要求和充满区距离表示式,利用iSIGHT软件,基于多岛遗传算法对角度参数进行了优化计算。结果表明:在不考虑其他影响因素的情况下,发射光束中心与弹轴的夹角αt取30°,接收视场中心与弹轴的夹角αr取34.5°,接收视场角θr取10°时能获得系统最小的充满区距离。所得计算结果可为水下单光束脉冲激光方位识别系统角度参数的设计提供理论依据。
In view of the confluence of underwater missiles, the distance and azimuth information of the target needs to be obtained in the short distance (greater than 10 m). In order to make full use of the emitted laser energy and increase the laser echo power, the angle of the underwater single beam pulsed laser azimuth recognition system The parameters were optimized. The relationship between echo power and system angle parameters was established by deducing the echo power equation of submarine pulsed laser azimuth recognition system. The angle requirements of underwater laser pulse azimuth recognition system and the filling area distance expression were obtained. Using iSIGHT Software, based on multi-island genetic algorithm to optimize the angle parameters. The results show that the angle αt between the center of the emitted beam and the elastic axis takes 30 ° without considering other influencing factors, the angle αr between the center of receiving field and the elastic axis takes 34.5 °, the receiving angle θr takes 10 ° When the system can get the minimum filling area distance. The calculated results can provide a theoretical basis for the design of the angle parameters of underwater single-beam pulsed laser azimuth identification system.
