英文摘要：

The statistical characteristics of Gaussian white noises and laser phase noises in this detecting system were analyzed. This paper is focused on the effect of these noises on the performance of the beam orienting system. The computer simulation results have shown high beam orienting precision provided low laser phase noises are maintained.
