摘　　要：确定搜救区域是开展海上搜救工作的基础。本文利用高频地波雷达返回的实时更新的海上风浪流数据,根据拉格朗日追踪法建立较为简单的漂移动力学模型。在空间上利用二维网格插值方法对漂移模型进行求解,并以随机粒子的运动过程模拟整个漂移运动,从而确定搜救区域。仿真结果表明,本系统可以较为精确地确定搜救区域,为海上搜救提供辅助决策信息。To determine the area is the fundamental work of maritime search and rescue. This article establishes a simple dynamic model,using data updated in real time of current,wind and wave returning from High-Frequency Surface Wave Radar,according to Lagrange drift tracking method. In order to determine the search and rescue area,the drift model was solved with 2 D grid interpolation method in space and the motion was simulated by the movement process of random particle. The simulation results show that this system can accurately determine the search area,so that assistant decision-making information for maritime search and rescue can be provided.
