An approach for automated passive sonar contact localization

July 23, 2019 | Categories: Publications


This work seeks to advance the state-of-the-art of fully automated detection, tracking, and localization of passive sonar contacts for large diameter unmanned underwater vehicles (LDUUV). A particle filtering track-before-detect-like approach is taken to develop three core algorithms to perform the above functionality. Each of the core algorithms are examined in pertinent respects using a real data set representative of newer high-resolution LDUUV sonar systems. The data set is highly cluttered, has varying noise levels, and consists of moving contacts that fade, cross, and merge in the bearing space. For comparison, a mainstay point-measurement-based particle filter approach using probabilistic data association is employed and shown to have greater difficulty addressing the scenario challenges than the developed approach herein.
