激光周向探测系统最佳脉冲频率与扫描转速

针对单光束激光周向探测系统中的扫描频率与电机转速的匹配难点问题，进行了单光束脉冲激光周向探测系统的目标探测研究。为提高单光束脉冲激光周向探测系统探测概率，建立了周向探测系统的弹目交汇模型，运用蒙特卡罗算法分析了激光脉冲频率和电机扫描转速对周向探测系统探测目标概率的影响，并选取最佳脉冲频率与电机扫描转速。根据最佳激光脉冲频率与电机扫描转速设计了原理样机并进行模拟探测实验。实验结果表明，当脉冲激光频率为20 kHz，电机扫描转速为30000 r/min时，在3 m探测距离范围内周向探测系统能有效探测目标。为单光束激光周向探测系统的最佳激光脉冲频率和电机扫描转速设计提供依据。

Abstract

Aiming at the problem of matching between the scanning frequency and the speed of the motor of a single beam pulse laser detection system, the research on target detection of the single beam pulse laser detection system is carried out. In order to improve the detection probability of the laser detection system, a model of the missile′s target intersection is established. The influence of laser pulsed frequency and motor scanning speed on the detection target probability of the circumferential detection system is analyzed by using Monte-Carlo method. According to the optimal laser pulsed frequency and motor speed, the principle prototype is designed and the simulating experiment is carried out. The experimental results show that in the case of 3 m detection range the detection system can detect the target effectively when the laser emission frequency is 20 kHz and motor speed is 30000 r/min, which provide the basis for the optimum laser emission frequency and the scanning frequency of the motor for the single pulse laser.
