Celestial background noise analysis for laser intersatellite links.
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.
