Abstract
The quality of the range image obtained by laser radar will directly influence the target profile reconstruction and the target identification, and the quality of the range image is mainly determined by the parameters of laser radar system. As a result, this paper concentrates on discussing the effect of laser radar's parameters on the quality of range image. To evaluate the quality of range image quantitatively, two parameters, the mean squared error of range (R-MSE) and peak signal noise ratio of range (R-PSNR), are introduced and a simulation program is developed to study the influence of system's parameters on the range imaging quality. The results show that for a given pulse width, there has an optimal bandwidth and threshold level, that make the range image has better image quality. Above results have important significance to optimize the parameter design of laser radar.
