基于组合圆锥构型的水下声学定位系统布站优化
Station Layout Optimization for Underwater Acoustic Positioning System Based on Combined-cone Configuration
摘要
Abstract
The theoretical minimum of the Geometric Dilution of Precision(GDOP)for target positioning cannot be achieved because of the coplanar constraint for the underwater station configuration.Therefore,the single-cone station configuration was extended to the combined-cone configuration to improve the observation matrix of underwater positioning system.However,the traditional optimization algorithms are still prone to local optimality and lower convergence efficiency.Therefore,an improved Adaptive Particle Swarm Optimization(APSO)algorithm was proposed.Firstly,a combined-cone configuration of underwater acoustic positioning system with coplanar constraints was proposed.The proposed configurations were theoretically proved to be superimposable,rotatable and GDOP rotation invariant.To address the problem of a single criterion for station layout optimization,a criterion based on the global GDOP for the underwater targets is constructed.Furthermore,an optimization algorithm based on APSO was introduced and applied to optimize the layout of the underwater acoustic positioning system in the combined-cone-shaped configuration.Finally,it is verified that the proposed APSO can enhance the global optimality and improve the convergence efficiency of the algorithm.And the positioning accuracy is improved.关键词
