摘要:

如何以较少的接收节点实现对监控区域的全覆盖是T-Rn多基地声纳部署的核心问题。本文将双基地声纳探测范围近似为两个圆, 将监控区域离散为接收节点可选位置, 提出改进的第二代非支配排序遗传算法(non-dominated sorting genetic algorithm Ⅱ, NSGA-Ⅱ)以得到更优的Pareto前沿实现一次优化, 基于效费比门限确定了接收节点数, 将接收节点数最少覆盖率最大的双目标优化问题简化为确定数量接收节点覆盖率最大的单目标优化问题, 采用考虑了Delaunay三角空洞修复的虚拟力算法对接收节点进行二次部署位置优化。仿真结果表明, 所提方法能够确定覆盖一定矩形区域所需节点数量,并通过优化部署基本实现全覆盖的目的。

Abstract:

How to achieve full coverage of the monitoring area with fewer nodes is the core issue of T-Rn multistatic sonar deployment. Bistatic detection area is approximated as two circles in this work. The monitoring area is discretized to optional positions of the receiving nodes, and an improved nondominated sorting genetic algorithm-Ⅱ (NSGA-Ⅱ) is proposed to obtain the Pareto front for first optimization. Then the number of receiving nodes is determined based on the cost-effectiveness ratio threshold and the dual target optimization problem with the minimum number of receiving nodes and the maximum coverage is simplified to a single target optimization problem with the maximum coverage of a certain number of receiving nodes. The virtual force algorithm (VFA) that considers Delaunay triangulation hole repair is provided to twice optimize the deployment position of receiving nodes. Simulation results show that the proposed method can determine the number of nodes to cover a certain rectangular area and basically achieve the goal of full coverage through optimized deployment.

Key words: multistatic sonar, optimal deployment, improved nondominated sorting genetic algorithm-Ⅱ (INSGA-Ⅱ), Delaunay triangulation hole repair
