基于Dubins路径的浮标搜潜阵型优化

Optimization of buoy submarine search array based on Dubins path

针对浮标搜潜浮标距离近、改航次数多的特点,将飞机机动能力纳入约束,结合浮标阵型、目标态势、飞行状态的相互影响,提出基于Dubins路径的浮标阵型规划方法。该方法按照Dubins路径调整浮标的布置角度和位置,避免了大幅度转向;并且在圆形阵和扇形阵基础上,令浮标至阵型中心距离随时间递增构建螺旋阵和螺线阵。仿真结果表明,优化的阵型减少了浮标消耗,缩短了航程和飞行时间,提升了浮标使用效率。螺旋阵的浮标消耗量和飞行时间分别缩短9%左右。

According to the characteristics of the short distance between two aviation search buoys and the large number of flight changes,this paper includes aircraft maneuverability in the constraints,and proposes a buoy array planning method based on Dubins path in combination with the interaction of the buoy array,target posture and flight status.This method adjusts the placement angle and the position of the buoy according to Dubins path,avoiding large turns.Besides,on the basis of the circular array and the fan array,the distance from the buoy to the center of the array increases with time,and a spiral array and an arc array are constructed.The simulation results prove that the optimized array reduces the number of buoys,shortens the range and flight time,and improves the efficiency of buoy use.The buoy consumption and flight time of the spiral array are respectively shortened by about 9%.
