海上线式巡逻落水空勤人员搜救区域模型与仿真

Mathematical Model and Simulation of the Search and Rescue Area for Accident Aircrew in Linear Patrol Pattern

海上落水空勤人员搜救是战时海上后方勤务保障的重要内容,确定搜索区域是海上搜救行动的前提和重要环节。任务类型、行动样式和信息的准确程度,决定了初始散布区域的大小和形状;而失事海域、自然条件和滞后时间,影响着搜救区域的大小和形状。建立初始散布区域模型,结合漂流速度、方向和参数误差,确定搜索区域模型,从而确定搜索区域散布,对确定搜救兵力和搜索行动样式具有重要意义。

Maritime search and rescue is an important logistics support during wartime.Determining the search area is the precondition and key link of search activity.The size and shape of the initial distribution area depend on task type,action pattern and accuracy of relative information,and the size and shape of the search and rescue area depend on the accident sea area,natural condition and delay time.The initial distribution model is constructed,the search and rescue area model is determined based on drifting speed,direction and parameter errors,and therefore the final distribution of aircrew is de⁃termined.It is valuable for determining action strength and action patterns.
