Analysis of Rotational Loss in Troposcatter Propagation

摘要

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。

Abstract: A computational method for the rotational loss in the troposcatter propagation is presented because the beams of transceivers antenna can not be along the circular path in trans-horizon passive detection. Because of the narrow beams of the transceivers in the troposcatter propagation, a Gauss function pattern of the antennas is assumed. An azimuth term is derived from the scatter receiver power and a path loss formula used for the beam rotation is given in this paper. Comparison with the experimental data presented in the literature, the two have good consistency. The rotational loss is simulated for the case that both antennas of the transmitter and receiver are not oriented on the great circle bearings. The proposed method is able to serve as a reference for designing the passive location system and detection system in the troposcatter trans-horizon propagation.
