Optimizing search patterns for multiple searchers prosecuting a single contact in the South China Sea

Abstract

Search and detection theory encapsulates a broad range of scenarios, from searching for lost car keys in a parking lot to prosecuting a submarine in the South China Sea. This research draws on oceanographic properties to develop a search radii for two surface ships, searching for a submarine at various speeds, utilizing one of three search patterns: in-line spiral search, in-line ladder search, and a multi-path ladder search. Analysis reveals which parameters yield the highest probability of detection in a 14nm by 14nm search area based on the oceanographic properties at 21N 119E.
