acoustic passive location array with four sensors 四元声阵列
Passive location is an important aspect in acoustical surveillance.In order to locate low altitude targets, the method of acoustic passive location with two arrays based on data fusion was presented. 摘要为了对低空飞行目标进行定位，提出一种基于数据融合的双基阵声测被动定位方法，并对定位算法和误差进行了理论分析和数值仿真。
Aiming at improving the precision of acoustic passive localization by small size array, we first derived eqs. 1 through 3 to describe the relation between time delay and target location. 根据声测被动定位对声学基阵提出的要求，给出了当基阵尺寸较小的情况下，影响声测被动定位精度的关键因素。
