【摘要】 本文讨论了大气湍流引起的强度起伏和相位起伏对激光雷达跟踪系统测角精度的影响。利用强度起伏导致的对数振幅方差和相位起伏导致的到达角方差，计算了强度起伏和相位起伏对跟踪系统的接收信噪比、角误差的影响。结果表明，大气湍流引起的角误差与仰角、距离等因素有关。更多还原

【Abstract】 In this peper, it is discussed about the laser radar’s angular tracking errors caused by atmospheric turbulence which results in intensity fluctuation and phase fluctuation. Then signal-to-noise ratio arid angular errors of the tracking system under the influence of intensity fluctuation and phase fluctuation are calculated with log-amplitute variance caused by intensity fluctuation and angle-of-arrival variance caused by phase fluctuation considered. It can be concluded from the result that angular errors caused by atmospheric turbulence relate to altitute angle, propagating distance,etc.更多还原
