HIGH PRECISION BEAMSTEERER BASED ON FIXED BEAMFORMING APPROACH BEAMPATTERNS

摘要

A beamsteerer for broadband energy source location, comprising an array of sensors, each for generating a signal vector within one of a plurality of sectors in a domain of interest, and a beamformer for receiving and multiplying each sign al vector by a set of optimal weight vectors to generate a plurality of beampatterns, each of the beampatterns being characterized by a null having high angular resolution, a nd detecting the source by selecting a maximum steering index.
