矢量线阵和标量弧线阵抗左右舷目标模糊性能分析

摘要

Traditional line array sonar has the problem of port/starboard ambiguity.To solve this problem,two signal processing models (p + vc and pvc) based on vector sensor uniform line array and different array arrangement models of scalar sensor arc array are proposed.The port/starboard discrimination capability of the different array arrangement methods and different signal processing methods are analyzed.The simulation results show that,both vector sensor uniform line array and scalar sensor arc array have advantages in port/starboard discrimination capability and observing efficiency.Though vector sensor uniform line array can distinguish port/starboard target,it will be disturbed in multi-targets environment.Scalar sensor arc array can distinguish port/starboard target completely if only it has certain central angle.%针对线阵声纳左右舷目标模糊问题,建立了基于矢量水听器直线阵p+vc和pvc两种信息处理模式以及标量水听器弧线阵不同布阵方式的抗左右舷目标模糊性能数学模型,分析了不同布阵方式以及不同信息处理模式的抗左右舷目标模糊性能,并进行了仿真计算.分析和仿真结果表明,矢量水听器直线阵和标量水听器弧线阵在分辨左右舷性能和观察范围上各有优势.矢量水听器直线阵虽然可分辨左右舷,但由于在一定扇面内分辨左右舷是依靠声纳方位历程图的明暗差异,在多目标情况下易造成声纳观察上的干扰;具有一定圆心角的标量水听器弧线阵,可以在更宽的扇面内具有抗左右舷目标模糊能力.
