Abstract

The invention discloses an improved maritime search and rescue region predicting method and an improved maritime search and rescue region predicting system. A dynamic drifting trajectory of a maritime search and rescue target object can be predicted according to existing meteorological and environmental data, a three-dimensional flow field, an improved AP98 air pressure model and a maritime search and rescue target drifting trajectory calculation model. The improved air pressure drifting model fully considers the uncertainty that motion in the side wind direction at each moment of a drifting target, so that a search and rescue region is more precise.

Description

technical field [0001] The invention relates to maritime search and rescue technology, in particular to an improved maritime search and rescue area prediction method and system. Background technique [0002] In recent years, with the expansion of the scale of marine development, my country's maritime foreign trade, tourism, aquaculture, resource mining and exploration, scientific research and a series of sea-related activities have flourished unprecedentedly, and the number of sea-related personnel has also increased rapidly. Increasingly frequent sea activities have greatly increased the frequency of sea accidents caused by human factors, and sea accidents are more concerned by people. Whether the maritime search and rescue operation can quickly and effectively search for the search and rescue target after the accident and implement rescue is of great significance to ensure the safety of personnel's life and property. [0003] The earliest research on search and rescue the...
