电视广播卫星地面接收系统

The Ground Reciving System of Television Broadcasting Satellite

本文简介了电视广播卫星地面接收系统,着重推导了未见诸已有文献中的最佳补偿角公式,并利用这个最佳补偿角,对接收系统作了重要改进,使地球上任何地域(卫星广播覆盖范围)设置的电动卫星接收天线都能达到统调,从而使地面卫星接收站对远离赤道上空36000km远的卫星广播节目均获得最佳接收状态。在国内外尚未见到这种产品。

This paper summarizes the ground receiving system of television broadcast satellite, and stresses in particular formula of the optimum compensation angle that we havenever seen in the previous documents. It also demonstrates that significant improvement on the receiving system can be made by means of this optimum compensation angle and that tracking of all receiving antenna set up any where on the earth (where satellite broadcasts cover) for power—driven satellites can be obtained the optimum so that the ground satellite stations attain receving couditions from the satellite broadcast 36000km away over the eqrator. This kind of product has seen neither home nor abroad.
