摘　　要：为提高对海上遇险目标的搜索效率,在搜救行动开始前需要对搜索目标的位置进行预测。在获得遇险目标的最后告知位置后,计算漂流轨迹可以预测搜救力量展开搜索时险目标的实际位置。通过计算各环境因素带来的漂移速度分量,进行矢量合成后可以得到遇险目标的漂移速度。对搜索目标遇险后的漂移轨迹进行预测,以此划定搜索区域。In order to improve the search efficiency of maritime distress targets,the location of the target needs to be predicted before the search begins.After receiving the last known pasition of the distress target,calculating the drift trajectory can predict the actual location of the target in distress as the rescue team launches its search.By calculating the drift velocity component caused by various enviromental factors,the drift velocity of the target in distress can be calculated after vector synthesis.By predicting the drift trajectory of the search target after distress,the search area can be delineated.
