ABSTRACT
In response to the problems of low direction-finding stability and low information restoration rate in shortwave monitoring stations, this paper proposes a shortwave monitoring system based on polarization sensitive arrays. Compared with traditional monitoring systems, the front end adopts a dual polarization antenna array for reception, a large aperture irregular sparse array, and the back end adopts an equalization synthesis process based on a multi-layer neural network structure, which enhances the ability of multi domain information interception and perception of shortwave signals, Enhance the anti fading reception ability of shortwave monitoring, improve the stability of direction finding and the ability to restore connotation information.
