Erasing false-location of two stations direction-finding cross location in multi-path and multiple sources environments

Abstract

Among methods of passive location to get positional information of radio sources, direction-finding cross location is convenient and often used. However, it has false-location in environments of multipath and multiple sources. This paper uses the technology of array direction-finding and adaptive beamforming for signal separation and recognition, based on signal correlation characters. All false-locations are erased successfully. Computer simulations show that this method is effective.
