Integrated probabalisitic data association tracker for enhanced active sonar detection

Abstract

Active sonar systems exhibit high false alarm rates that reduce their usefulness in target detection. An idea to reduce false alarm rates is to track the hypothetical targets from the sonar system and reject false detections that do not generate a reasonable track. The IPDA algorithm includes a procedure for estimating the probability a track is a true track. This estimate is investigated as a detection statistic. The use of IPDA ability is compared to a single pulse detector and to a multistatic active sonar system using IPDA to combine measurements from different sensors as well as different scans. © 2005 IEEE.
