Research on the Efficiency and Application of Ship-Helicopter Cooperative Search

Abstract

In view of the maritime search and rescue problem, this paper analyzes the status and research results of maritime search and rescue, and uses the cooperative search of ship-ship as the main search method to study the optimization problem of search route. This paper designs three evaluation indexes of efficiency which include area searching time, key area searching time and the number of targets searched within a certain time, and builds three common mathematical models of cooperative parallel line search, spiral search and fan search. This paper compares the efficiency of the ship-helicopter cooperative searching routes through simulation analysis, then gives the suggestions of choosing the optimal cooperative searching route. Further research on the application of the three search routes to the actual rescue situation affected by the wind direction, the number of targets, and the presence or absence of location notification. It preliminarily designs the mode of combining UVAs and ships, trying to put forward feasible methods to improve the searching efficiency.
