摘要
由于深空测控站具有天线口径大、工作频段多、接收灵敏度高、辐射功率大、工作时间长等特殊性,与一般地球卫星测控站选址相比,必须对站址周围电磁环境、地质、水文气象等方面提出更高的要求。本文在对国外深空测控站选址要求进行研究的基础上,以类似白高斯噪声(WGN)的干扰信号为分析对象,探讨了深空测控站无线电干扰保护门限的计算方法。
Site selection requirements for Deep Space TT&C Stations(DSS) are different from conventional ground TT&C Station because DSS stations have their distinct characteristics,such as large antenna aperture,multiple operation frequency bands,high receiver sensitivity,stronger eradiate power and long operation period.Therefore,it is very important to take into account the higher requirements of electromagnetic environment,geology and hydro-meteorology around the site for a DSS station.After investigation of site selection requirements for an overseas DSS station,this paper assumes that the interference signal is White Gaussian Noise(WGN) and describes the calculation method of wireless interference protection threshold for DSS stations.
