摘　　要：为了实现扫描式激光雷达对工作视场的全覆盖扫描,根据激光光束参数和李萨如扫描方式的特点,提出了一种激光雷达扫描参数设计和仿真分析方法。给出空间交会测量用扫描式激光雷达的测量原理,分析了李萨如扫描方式激光雷达的特点,根据激光雷达测量系统的总体指标,采用数学分析的方法计算出李萨如扫描视场参数。提出了一种数字仿真验证方案,对激光雷达李萨如扫描视场参数进行验证,仿真不同的参数下激光雷达的视场扫描覆盖率。实验结果表明提出的李萨如扫描视场参数设计方法有效,能够确保激光雷达实现全视场100%的空间扫描覆盖率,进而保证空间交会测量任务的安全。In order to achieve full coverage scanning of the working field by scanning laser radar,a laser radar scanning parameter design and simulation analysis method is proposed based on the characteristics of laser beam parameters and the LiDAR scanning mode.The measurement principle of scanning laser radar for space rendezvous measurement is provided.The characteristics of the LiDAR scanning mode are analyzed,and the LiDAR scanning field parameters are calculated using mathematical analysis methods according to the overall indicators of the laser radar measurement system.Finally,a digital simulation verification scheme is proposed to verify the LiDAR scanning field parameters and the scanning coverage of the laser radar under different parameters are simulated.Experimental results show that the LiDAR scanning field parameter design method proposed in this paper is effective,ensuring that the laser radar achieves 100%spatial scanning coverage of the entire field of view,thereby ensuring the safety of space rendezvous measurement tasks.
