中文摘要:
      通过对目前常用的空间声目标定位方法的分析,针对四元平面方阵定距精度差的问题,提出了立体六元探测基阵的传感器布置方案,即在四元平面方阵的基础上,增加两个声传感器。根据被动声定位原理推导了定位算法,分析了时延估计误差对定位精度的影响,并进行了数字仿真实验,与四元平面方阵相比取得了较好的定位效果。
英文摘要:
      Aimed at the problem of low location precision of a four-element-square-array,a design of six-element detection array composed of adding two acoustic sensors to a four-element-square-array is presented.The location algorithm is deduced based on the theory of passive acoustic location.The influence of time delay estimation error on the location precision is analyzed.Simulation results show that the design has a good location performances compared with the four-element-square-array.
