激光到达角误差修正方法研究

由于大气介质的不均匀性,导致大气折射率不再是常数,使得激光在大气中传播时产生折射效应,最终使激光束到达角产生误差,影响系统的通信性能.为了减小到达角产生的误差,提高系统的性能,提出了一种利用纯转动拉曼激光雷达修正对流层目标定位误差的方法,根据角度折射误差来调整光源仰角的方法.通过对新方法仿真计算证实,在进行远距离光通信时,经过大气折射误差修正后,可以在很大程度上提高光通信的速率,减小误码率.

Study on The Arriving Angle Error Correction Method of the Laser Transmitting

Becauce inhomogeneity of the medium in the atmosphere,causing atmospheric refractive index is no longer a constant,making the transmission of laser in the atmosphere generated refraction effects,ultimately resulting laser beam angle of arrival errors affect communication performance of the system.In order to reduce the angle of arrival resulting from error and increase system performance,a pure rotational Raman lidar tropospheric to revised target location error method was given,according to the angle error...
