摘要
激光模拟射击技术具有成本低、安全性高、模拟效果强等优势,被应用在日常军事训练中。针对远场光斑较大的问题,设计了一种自适应单兵训练激光模拟射击器。根据Mie理论计算大气造成的激光功率衰减,研究光束距光轴质心的距离与该位置处的光功率之间的对应关系,建立相应的光束模型;分析在120~200 m之间的光功率与探测器阈值光斑直径的函数关系,设计激光器的驱动电路,建立激光器阈值光斑自适应控制理论,并基于STM32的PWM输出实现对远场光斑的调控,将探测器的阈值光斑直径从大向小调节,从而调整模拟器远场射击的杀伤范围。最后通过试验对自适应控制体系进行验证,将200 m处的阈值光斑调节至理想状态,解决了远距离一枪命中多人的难题,提升模拟器的可靠性、便捷性、实用性。
Laser simulation shooting technology has the advantages of low cost,high safety,and strong simulation effect,which has been used in daily military training.Aiming at the problem of large far field light spot,an adaptive laser simulator for soldier training is designed in this paper.According to Mie theory,the laser power attenuation caused by atmosphere is calculated.the corresponding relationship between the distance of beam from the optical axis centroid and the optical power at this position are studied,and the corresponding beam model is established.The functional relationship between the optical power between 120~200 meters and the threshold spot diameter of the detector are analyzed,the driving circuit of the laser is designed,the adaptive control theory of the threshold spot of the laser is established,and the far-field spot is regulated based on the PWM output of STM32.Through adjusting the threshold spot diameter of the detector from large to small,the kill range of the simulator's far-field firing is adjusted.Finally,the adaptive control system is verified through experiments,and the threshold light spot at 200 meters is adjusted to the ideal state,which solved the problem of hitting multiple people with a single shot from a distance,which improves the reliability,convenience,and practicability of the simulator.
