基于跟踪起始准则的多基地声呐阵位优化算法

针对水下区域监视多基地声呐（如浮标等）发射、接收节点阵位布置问题，提出了一种基于跟踪起始准则的多基地声呐阵位优化算法。该算法首先在分布式和集中式两种多基地融合处理模式下，推导了目标跟踪起始概率计算准则，然后，基于区域目标成功跟踪起始覆盖率，建立了多基地声呐阵位优化数学模型，并采用粒子群算法来优化求解该非凸数学模型，从而得到全局最优的多基地声呐发射-接收阵位。仿真结果表明，在两种多基地融合处理模式下，优化后多基地声呐节点阵位，其区域目标跟踪起始覆盖率比典型经验方案有较大提高。

An optimization algorithm for multistatic sonar placement based on track-initiation criteria

In this paper, an optimization algorithm for multistatic sonar placement based on track-initiation criteria is proposed to solve the problem of monitoring underwater placement of the transmitters and receivers in multistatic sonar system. Two criteria are firstly derived for computing track-initiation probability under distributed and centralized tracking fusion modes in multistatic sonar system. Then, a mathematic model of placement optimization of multistatic sonar based on successful target track-initiation coverage rate is established, and the particle swarm optimization algorithm is used to obtain the optimal solution for the un-convex mathematic model, which is the global optimal placement for sources and receivers in multistatic sonar system. The simulation results indicate that the successful target track initiation coverage rate of the proposed method is much improved in comparison with the empirical methods under two tracking fusion modes in multistatic sonar system.
