Abstract
DETECTION OF BROAD-BAND TARGETS ON SONAR TIME-BEARING DISPLAYS REQUIRES THAT A THRESHOLD BE ESTIMATED. THE ESTIMATE IS DEGRADED BY LEAKAGE THROUGH THE BEAM-FORMER SIDELOBES. TIME-BEARING COMPENSATION (TBC) DECREASES THE EFFECT OF SIDELOBE LEAKAGE, AND THEREBY IMPROVES THE THRESHOLD ESTIMATE AND DETECTION PERFORMANCE. THE THEORETICAL BASIS FOR TBC IS AN OPTIMALITY CRITERION WHICH LEADS TO A FORMULA FOR IMPROVING THE BEAMFORMER OUTPUTS. THE GREAT ADVANTAGE OF TBC IS THAT IT DOES NOT REQUIRE ACCESS TO THE BEAMFORMER INPUTS. A DEMONSTRATION AND EVALUATION OF THE TBC CONCEPT IS PROPOSED.
