In order to analyze the performance of the imaging lidar system, the numerical simulation model for imaging laser radar is presented. This model is based on the laser radar principles, and it concerns lidar range equation, noise model, SNR (Signal-to-Noise Ratio), imaging model,etc. It aims to find out the correlation between the various outside conditions and the model parameters, and thus to predicate how the outside conditions affect the performance of the Lidar system. With this model, a simulation software is built to operate the simulation of lidar system. Results show that numerical simulation can help scheme designing and performance improving of the lidar system.
