Abstract

The celestial background (CB) has a potential significant influence on the laser intersatellite links (ISLs). A simple method to analyze the power and statistical distribution of the CB noise received by optical terminals is described for application to the ISLs. In order to evaluate the CB noise of the ISLs, an emulation analytic system is established. The CB noise of two adjacent interorbital plane ISLs and two intraorbital plane ISLs of a low Earth orbit satellite in the constellation is analyzed. The system can also be applied to examine the CB noise of other ISLs. The simulation results conduce to the performance evaluation of the ISLs.

摘要

天体背景（CB）对激光星间链路（ISL）可能有重大影响。本文描述了一种分析光终端接收的CB噪声功率和统计分布的简单方法，用于ISL。为了评估ISL的CB噪声，建立了一个仿真分析系统。分析了星座中一颗低地球轨道卫星的两个相邻轨道平面ISL和两个轨道内平面ISL的CB噪声。该系统还可用于检测其他ISL的CB噪声。仿真结果有助于对ISL进行性能评估。
