摘　　要：依据漫反射目标探测的信号与噪声的统计特征,对相干激光雷达的探测信噪比、接收灵敏度等关键参数进行仿真分析与研究。结果表明,接收灵敏度与探测概率和虚警率性能要求密切相关,同时也会受到目标速度动态范围以及所选取的波长的影响,采用多次探测的方式对接收灵敏度有明显的提升作用。研究结果对相干激光雷达的总体设计具有重要意义。According to the statistical characteristics of signal and noise of diffuse-reflection target detection analysis is made to the key parameters such as signal to noise ratio and receiving sensitivity of the coherent lidar.The research results show that:1)The receiving sensitivity is closely related to the requirement of false alarm rate and detection probability as well as the dynamic range of target velocity and the detection wavelength;and 2)The sensitivity can be significantly improved by the mode of multiple detections.The research result is of great significance for the system design of coherent lidars.
