摘　　要：分析出瞳扫描方式扫描视场角与激光雷达光学系统参数的关系，认为最大扫描视场角比主天线望远镜静态视场角小。在信号过程线性的前提下，根据强度象的瑞利判据建议扫描激光雷达角分辨本领公式。The relation of scanning vision angle with exit pupil mode versus the parameters of optical system for the laser radar is analyzed and think that the maximum scanning vision angle is smaller than static vision angle of main antenna telescope.With the premise of linearizing for the signal process,an equation for the angular resolution of the scanning laser radar is recommended according to the Rayleigh′s criterion for the intensity image.All the main conclusions have been demonstrated with experiments.
