摘要
提出一种简单高斯模型描述局部波前畸变,并在此基础上以透射式光学天线为例,研究星间光通信中局部波前畸变对对准精度的影响。理论分析和仿真结果表明,局部畸变半径、畸变深度以及畸变位置是对准偏差的3个主要影响因素。
In order to simplify the calculation, Gaussian model is proposed to describe localized deformation, based on which, taking transmission-type antenna for example, the effects of localized deformation on pointing error is researched. The results of analysis and numerical emulation show that pointing error depends on three parameters of localized deformation, deformation radius, deformation deepness, and distortion position. Pointing error increases monotonously as distortion radius rises. With the distance between the distortion and beam center, pointing error firstly increases and then decreases monotonously.
