【摘要】：為提高海上搜救的成功率,最大限度地減少生命和財(cái)產(chǎn)損失,需獲得精確的漂移模型,并快速確定包含搜救目標(biāo)的最小搜尋區(qū)域。對(duì)此,分析海洋環(huán)境、目標(biāo)漂移特性等因素的不確定性對(duì)漂移運(yùn)動(dòng)的影響,提出一種新的風(fēng)壓差翻轉(zhuǎn)率計(jì)算方法,并運(yùn)用該方法建立搜救目標(biāo)漂移模型。通過仿真試驗(yàn),基于所建立的漂移模型,分別用解析法和Monte Carlo法對(duì)失事船舶搜尋區(qū)域進(jìn)行估計(jì)。結(jié)果表明:風(fēng)壓差翻轉(zhuǎn)率計(jì)算方法可提高漂移模型的精度;基于所建立的漂移模型,使用Monte Carlo法估計(jì)的搜尋區(qū)域能最大程度地包含搜救目標(biāo)且面積小。
[Abstract]:In order to improve the success rate of maritime search and rescue and minimize the loss of life and property, it is necessary to obtain an accurate drift model and quickly determine the minimum search area containing search targets. In this paper, the influence of the uncertainty of ocean environment and target drift on drift motion is analyzed, and a new method of calculating wind pressure difference turnover rate is proposed, and the drift model of search and rescue target is established by using this method. Based on the established drift model, the search area of shipwrecked ship is estimated by analytical method and Monte Carlo method. The results show that the precision of the drift model can be improved by calculating the wind pressure difference turnover rate, and the search area estimated by the Monte Carlo method can contain the search target with small area to the maximum extent based on the established drift model.
