水下动态航路规划不仅需要考虑适配区的选择,还需要进行实时目标探测和有效避障,这样才能保证潜器的导航安全。文中提出一种同时考虑适配区选择和目标探测的水下航路规划方法,在重力梯度特征空间中基于支持向量机进行适配区的选择,利用重力梯度反演进行目标探测。该方法使潜器既能在适配区航行时进行有效定位,又能避免触碰暗礁和运动潜器等障碍物。仿真分析证明此方法有效。
水下動態航路規劃不僅需要攷慮適配區的選擇,還需要進行實時目標探測和有效避障,這樣纔能保證潛器的導航安全。文中提齣一種同時攷慮適配區選擇和目標探測的水下航路規劃方法,在重力梯度特徵空間中基于支持嚮量機進行適配區的選擇,利用重力梯度反縯進行目標探測。該方法使潛器既能在適配區航行時進行有效定位,又能避免觸踫暗礁和運動潛器等障礙物。倣真分析證明此方法有效。

In dynamic underwater path planning ,consideration should be given to not only adaptive are-a selection but also real-time target detection and effective obstacle avoidance ,w hich can ensure the safety of the submarine .This paper proposes an approach to underwater path planning which consid-ers both adaptive area selection and target detection simultaneously .With the approach ,adaptive area selection is based on support vector machine and target detection is based on gravity gradient inver-sion .The approach makes it possible to effectively position the submarine while navigating in adaptive area and it can also prevent the submarine from striking on reefs or other moving submarines .Simula-tion results show that the proposed approach is valid .
