ABSTRACT:
An algorithm for detecting and tracking dynamically-related sets of unstable passive sonar signals is disclosed. The algorithm detects, enhances, tracks and displays both stable and unstable passive sonar signals, while organizing them into dynamically-related groups. The algorithm is implemented as part of a general purpose digital computer/peripheral system that performs:
