摘要

提出了一种深空光通信扩展信标的跟踪方法。该方法的原理是在航天器上存储一幅信标图像作为参考

把实际信标图像看成参考信标图像和附加高斯白噪声和的形式

基于离散傅里叶变换和相位相关技术对信标的旋转因子和平移因子进行计算。理论分析与仿真结果都表明

该方法可以把跟踪误差控制在0.5个像素以内。针对不同的信噪比对该方法进行仿真

计算误差并没有显著的变化

表明该方法具有良好的抗干扰性

能满足光通信链路实时运行的要求

是一种可行的方案。

Abstract

A extend-beacon tracking method for deep space optical communication was proposed

and the operational principle of the method was given.By storing a beacon image in aircraft as reference and regarding actual beacon image as the sum of reference image and additive Gaussian white noise

the values of rotation and translation for beacon image were calculated according to phase correlation and DFT(Discrete Fourier Transfer). The theory analysis and computer simulation show that the tracking error can be constrained below 0.5 pixels. The computer simulation based on different SNR (signal noise rate) indicates that the change of a calculation error is little

it shows that the method has the advantage of rejecting noise and it is a feasible strategy for deep space optical communication.
