| 摘 要： | 本文介绍了一种采用圆周阵对目标声源进行被动定位和跟踪的方法。与线阵不同，圆周阵可对目标进行全方位跟踪，且测距精度不受目标方位变化的影响。文中给出了圆周阵的测距、测向公式，并从理论上分析了测距性能，计算机仿真结果验证了理论分析的正确性。

| Abstract: | This paper presents a method of passive locating and tracking an acoustic source by using acircular array,The circular array is differnt from line array in that it can track target at all of bear-ing,and range estimation variance is not affected by target bearing.The formulas of calculating rangeand bearing for circular array are derived,and the ranging performance is analysed theoretically,Thesimulation results show that the theoretical analysis is correct. |
