摘　　要：为了研究大气米散射激光雷达系统的光学结构参数对探测结果的影响,采用模拟计算方法得到各种参数条件下相对接收信号强度随距离的分布图,并对相应的校准与调试方法做出探讨。结果表明,为达到设计要求,100m处激光束的光斑须调整到不超过25mm;对1000m处的硬目标校准时,发射与接收轴间夹角误差为2.2μrad,此时激光束发散角包含于望远镜的接收视场范围内。To study the influence of the system optical parameters on the received signal, the profile of signal-to-range under several parameters were given after simulation. It turned out that the laser facula must be adjusted to be smaller than 25mm. Aiming at an object 1000m away,when the error of the angle between the transmitter and receiver axes was 2.2μrad, the emission angle was included in the received field of view of the telescope.
