摘要
Abstract
In order to make the airborne conformal array have better multi-path suppression ability and improve the communication quality,it is necessary to carry out beamforming research in combination with the complex multi-path channel to earth.In this paper,the adaptation of multipath channels was analyzed from typical scenes such as offshore mountains,tropical oceans and complex mountains,and the modeling of high-speed multipath channels to ground was completed.Then,a conformal array antenna model was es-tablished which is suitable for airborne environment,and the polarization and aperture effects were fully considered.Finally,the receiving LSMI beamforming simulation was carried out under the narrowband as-sumption,and the received beam pattern and beam scanning results of the multi-path channel array were ob-tained,and the results are compared with the traditional uniform line properties under multi-path and non-multi-path conditions.The results show that the complex multipath channel of airborne to ground commu-nication can significantly weaken the performance of conformal array filtering in airspace,resulting in at least 3 dB performance degradation.关键词
