一种扫描式六象限激光探测系统弹目交会算法研究

针对某旋转式火箭弹定向战斗部定向探测与起爆控制系统，分析了扫描式六象限激光探测系统的构成和工作原理，提出了由激光束螺旋角计算弹体转速的方法，建立了弹体转速数学模型、弹目相对运动方程及相互间的迭代解耦算法，并编写Fortran程序进行仿真。仿真结果表明，建立的交会算法可以计算得到弹体转速、弹目相对运动速度、目标脱靶量、最佳起爆延迟时间、最佳起爆方位角等参量，且误差分析显示探测方位角误差满足定向战斗部的方位探测精度要求。

Research on Projectile-target Encounter Algorithm for Six-quadrant Scanning Laser Proximity Fuze Sensor

Based on the fuze sensor and detonation control system of an aimiable warhead of a spinning rocket, the construction and functional mechanism of the six-quadrant scanning laser fuze sensor is analyzed. A method of measuring the rocket rotational speed based on the spiral angle of laser beam is proposed. A mathematic model of rotational speed and a projectile-target relative motion equation are deduced, which can be solved by iterative decoupling algorithm. Simulation based on the Fortran program is conducted, and the optimal detonation time delay, optimal detonation azimuth angle and miss distance are obtained. The error analysis shows that the detected azimuth error meets the requirement of detecting accuracy.
