Analysis of Rotational Loss in Troposcatter Propagation

  • 摘要: 針對對流層超視距無源探測中可能遇到收發(fā)天線波束不能對準(zhǔn)的情形,該文給出了對流層散射傳播偏移損耗的理論計算方法。利用收發(fā)天線窄波束的特點,假定高斯型的天線方向性函數(shù),建立了對流層散射傳播接收功率中的方位項函數(shù),得到了散射傳播偏移損耗理論公式。與文獻中的試驗數(shù)據(jù)比較發(fā)現(xiàn):二者具有較好的一致性。另外對收發(fā)天線均偏離大圓路徑情形下的偏移損耗進行了仿真。此種傳播損耗計算方法,可為對流層超視距傳播的無源定位與探測系統(tǒng)設(shè)計提供參考。
