【摘要】:研究了星地激光通信中地球背景輻射及其抑制技術(shù)。推導(dǎo)出了不同軌道處星上終端的地球背景輻射入瞳功率理論公式,提出了固有雜散輻射的概念,并對其作了理論推導(dǎo)。針對一個典型的終端對其地球背景輻射進(jìn)行了理論計算,并設(shè)計了不同形式的遮光系統(tǒng)。最后利用光學(xué)仿真軟件LightTools對不同軌道高度、不同遮光系統(tǒng)形式的星上終端的雜散輻射進(jìn)行了仿真,得到了軌道高度以及遮光系統(tǒng)形式對雜散輻射的影響曲線,并對其作了分析。為星地激光通信中星上終端的地球背景輻射提供了理論依據(jù),為星上終端的遮光系統(tǒng)設(shè)計提供了仿真依據(jù)。
[Abstract]:The earth background radiation and its suppression technique in satellite-ground laser communication are studied. This paper deduces the theoretical formula of the power of the earth background radiating into the pupil of the terminal on the satellite in different orbits, puts forward the concept of inherent stray radiation, and deduces the theory of the inherent stray radiation. For a typical terminal, the earth background radiation is calculated theoretically, and different shading systems are designed. Finally, the optical simulation software LightTools is used to simulate the stray radiation of the satellite terminal with different orbital heights and different shading system forms. The influence curves of orbit height and shading system form on the stray radiation are obtained and analyzed. It provides the theoretical basis for the earth background radiation of the satellite terminal in the satellite-to-ground laser communication, and provides the simulation basis for the design of the optical shading system on the satellite terminal.
