中文摘要:
      文中提出一种适用于深海条件下并已知各项有关环境参数时,利用七元小型矢量立体阵,借助测定目标辐射噪声由不同途径自声源到达接收点的天顶角及方位角的结果,依据射线声学方法求得目标方位、距离和所在深度的被动定位方法。给出了矢量阵依多级子原理进行波束形成的计算公式,并就一种简单水文模型,给出解析计算公式。
英文摘要:
      In paper a method of passive positioning of target, using small 3-D vector sensor array composed by seven sensors, had been proposed, which can be used in deep sea cases, provided the relevant environmental factors are known. The method depends on measurements about zenith and azimuth of noise coming from target to the array along different pathes, and the result can be given by means of geometric acoustics. In paper formulas for beamforming of vector sensor array, when using mathod of multi-pole, are given, and analytic formulas for result computation are also given as example for one simple hydrological model.
