激光多档定距引信系统参数综合优化

为配合多模战斗部的多位置点起爆要求,激光近炸引信需实现在1~25 m之间的多档定距,对于非同轴的激光引信,其探测距离范围与系统参数的选取密切相关。基于系统探测距离要求,建立非同轴系统工作距离计算模型,分析激光引信系统参数变化对最近工作点和最远工作点的影响,以接收偏角和发射接收中心距为变量,在满足约束条件的情况下,利用多岛遗传算法对变量进行优化。优化结果表明:在满足约束条件的情况下,接收偏角最小为90.97°,中心距为0.03 m。搭建激光多档定距实验平台对优化的系统参数进行验证,实验结果表明,设计系统参数能够满足多档定距要求。研究可为激光多档定距引信系统参数设计提供参考。

Comprehensive parameter optimization of laser fuze system with multi-ranging

In order to meet the multi position initiation requirements of multi-mode warhead, the laser fuze needs to simultaneously achieve multi-ranging distances from 1 m to 25 m. For the noncoaxial laser fuze, the range of the detection distance is closely related to the system parameters. Based on system detection distance requirements, the working distance calculation model of the noncoaxial system was established, the influence of the system parameter changes of the laser fuze on the nearest working point and the furthest working point was analyzed. The receiving deflection angle and the center distance between the transmitting and receiving system were variables. In the case of satisfying the constraints, the multi-island genetic algorithm was used to optimize the variables. The optimization result shows that, under the condition of satisfying the constraints, the minimum receiving deflection angle is 90.97°, and the center distance is 0.03 m. The experimental result shows that the designed system parameters can completely meet the requirements of multi-ranging distance. The research can provide reference for the parameter design of laser fuze system with multi-ranging.
