Abstract

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.
