摘　　要：船舶在极区航行时会受到海冰带来的阻碍和安全风险,如何能在高效完成指定航行任务的同时,更好地规避冰撞、冰困风险,是极地船舶驾驶人员长久以来需要面对的难题。该文基于微波遥感和卫星测高等技术途径所获数据,反演得到海冰厚度、密集度等信息,建立航行环境信息栅格场和邻域网;采用改进的启发式搜索算法,创新提出考虑船舶冰区航行能力与结构安全风险双重限制下的判定模型,并建立极地航线自动规划方法的系统框架。研究结果表明该方法有效考虑了海冰环境、船舶冰区航行能力对航线规划的影响,该成果有助于加速极区航线自动规划技术面向实用的迭代,同时在极地装备航行任务想定推演、效能评估方面也具备较高的应用价值。The sea ice imposes hinderance and safety risk to the navigation of ships in polar regions.It has long been a challenge for polar ship navigators to efficiently complete designated navigation tasks while avoiding risks of ship-ice collisions and being trapped in ice.A navigation environment information grid field and neighborhood networks are established based on the sea ice thickness and concentration data obtained through data inversion based on the high-tech approaches such as microwave remote sensing and satellite measurement.An improved heuristic search algorithm is employed to propose an innovative judgment model considering both the ice navigation capability of ships and structural safety risks.A systematic framework has been established for automatic polar route planning.The results show that the current method effectively considers the impact of the sea ice environment and the ice navigation capability of ships on route planning.The achievements can help accelerate the practical iteration of automatic polar route planning technology and have high application values in the scenario deduction and efficiency evaluation of polar equipment navigation missions.
