中文摘要:
      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。
英文摘要:
      In this paper a passive method is presented for locatig and tracking a noise source by use of circular array.which is different fron linear array,It can track target at all of bearing and the variance of range estimation is not depended on target bearing. The formulas of calculating range and bearing for circular array are derived,and ranging performance are analysed theoretically.The simulation results show that the theoretical analysis is correct.
