It is crucial to design a rational and effective lidar system for the research of the lidar. The relationship between many parameters must be considered adequately. The laser source and the deteetor and some other components were chosen on the basis of the required index. In order to analyze the performance of the lidar system, the numerical simulation model for lidar was presented. This model was based on the lidar principles, and it concerned lidar range equation, noise model, etc. The effect on lidar caused by changes of important weather and system variables was analyzed and discussed with the LOWTRAN. With this model, a simulation software was built to operate the simulation of lidar system. Results show that numerical simulation can help scheme designing and performance improving of the lidar system.
