激光探测系统仿真技术研究

摘要

激光探测技术能被广泛用于自行高炮武器系统的目标探测与识别系统中.测距功能是激光探测系统中最主要的内容,但是由于目标结构复杂,仿真建模难度很大.为了解决激光测距仿真问题,以某高炮系统激光测距机为对象,提出了一种目标等效圆模型的激光探测系统方法.以目标当前时刻航路参数和跟踪误差为依据,对目标反射能量、激光发射能量、大气之间的关系建立测距与回波的仿真模型,并进行仿真.仿真结果表明,所建模型能够定性、定量反映激光测距在实际环境中的性能指标.可为防空火控系统的激光测距提供了有效手段.%Because of laser detection technique's superior performance, it has been widely used in target detection and identification system of AAA gun. Ranging is the most important content in Laser Detection System. But the target structure is complex, and simulation modeling is difficult. In order to improve the performance, in this paper, we took a certain type of fire control system of AAA gun as the study object, and proposed the scheme of the Laser Detecting Simulation System based on target equivalent circle model. On the basis of the current target route parameters and the target tracking error, and the relationships of the energy reflected by objectives, laser energy and the atmosphere were researched. And the model of its distance and the laser echo was built. Simulation results show that the model can qualitatively and quantitatively reflect the laser range finder performance in the actual environment, and can be used for the simulation of laser range finder in fire control system.
