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20kHz,电机扫描转速为30000r/min时,在3m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。
In view of the difficulty of matching the scanning frequency and the motor speed in the single-beam laser circumference detection system, the target detection of the single-beam pulsed laser circumference detection system is studied. In order to improve the probing probability of single beam pulsed laser circumferential detection system, a projectile intersection model of circumferential detection system was established. The influence of laser pulse frequency and motor scanning speed on the detection probability of circumferential detection system was analyzed by Monte Carlo algorithm. And select the best pulse frequency and motor scan speed. According to the best laser pulse frequency and the motor scanning speed, a prototype was designed and simulated. The experimental results show that when the pulse laser frequency is 20kHz and the motor scanning speed is 30000r / min, the detection system can detect the target effectively within 3m detection range. It provides the basis for the design of the best laser pulse frequency and the motor scanning speed of single-beam laser circumferential detection system.
