Determination of Optimal Ping Strategy for Random Active Sonar Search in a Counterdetection Environment

摘要

This thesis documents the analysis of one-on-one ASW encounters between a surface searcher using active sonar and an evasive target submarine. The analysis is based on data generated by a computer simulation of the relative motion of the two adversaries over time. The specific objective of this analysis is to prescribe a strategy for selecting a searcher ping interval which maximizes the probability of detection in an environment which favors the target's counter-detection ability. The Scenario: A single surface ship is assigned to search for a submarine target of interest using active sonar within a region several hundred thousand square miles in area. The acoustic environment is considered homogeneous throughout the area. Thus for any particular case, the sonar range is considered a constant. Keywords: Regression analysis; Mathematical models.
