摘要
一、引言 激光束在洁净大气中传播时，由于湍流的影响，光束波阵面到达角将作随机起伏，光束整体将作随机抖动。这些湍流效应严重影响激光大气通信和大气参数的光学法探测，所以人们对此作了大量研究。但是，对激光束在雨和湍流同时存在时传输的到达角起伏和湍流大气中双频光束抖动相关函数研究很少．而这些问题在实际工程应用中常涉及到。
Using the method of small perturbations, we have obtained the wander freqtteney correlation of beam light in turbulent atmosphere and using the Markov approximation, wc have obtained a work wave length at which the beam wander is maximtm. These results show that beam wander depends on the wave length of optical source. We also have discussed the effect of the rain on the fluctuation of the angle of arrival.
