| 摘 要： | 针对五元空间声传感器阵列被动声定位中存在着对目标声源位置估计偏差较大的问题,提出了一种七元空间声传感器阵列被动声定位的数学模型,通过数学推导与计算给出了定位公式.利用误差分析理论对比了两种阵列的定位性能,得出了定位偏差与目标声源的俯仰角,方位角和时间延迟量的关系.使用这2种声阵对100个假设目标声源位置点进行估计计算,通过计算机仿真得出了七元空间声阵具有较高定位性能.

| Abstract: | Aiming at the large deviations of estimated localization of sound source by the five-element acoustic array passive acoustic positioning method,this paper proposed a model of seven-element acoustic array and a mathematical formula to solve the problem.Based on error analysis theory,the location performances of two acoustic arrays were compared in order to find the better method and the relationship between positioning deviation,azimuth,angle of pitch and delay time.Through computer simulation of one hundred random object sound source location,it showed that the seven-element acoustic array has the better performance of location. |
