考虑望远镜存在跟踪随机抖动及大气湍流引起的光斑抖动等因素，推导出新的激光测距方程。采用数值模拟的计算方法，研究分析激光发散角、望远镜跟踪随机抖动和大气湍流引起的光斑抖动对回波强度的影响，得出望远镜跟踪抖动及激光发散角是影响测距系统性能的重要因素。

In this article a new laser-radar ranging equation is deduced. This equation takes into consideration the tracking jitter of a telescope and the beam jitter caused by atmosphere turbulence. Numerical simulation is applied to the equation on echo intensity; this paper also explores in detail factors such as laser divergence angle, tracking jitter of telescopes and beam jitter caused by atmosphere turbulence. Analyses indicate that both tracking jitter and beam jitter are crucial factors for the performance of a ranging system.
