介绍了空中目标激光雷达一维距离像的回波模型,分析了影响探测系统性能的因素,仿真分析了大气衰减、接收系统噪声和激光散斑效应对目标成像分辨率的影响。用原理性实验验证了分析结果，得出了结论。基于此给出了建议。

An echo model of one-dimensional lidar range profile of airborne targets is introduced. The factors which affect the property of the detecting system are analyzed. The influences of atmospheric attenuation, receiving system noise and laser speckle effect on the resolution of target images are analyzed and simulated. The analysis results are verified by the principle experiment and the conclusion is obtained. Based on this, the suggestions are presented.
