【摘要】 文中设计了一种六元十字阵被动声定位系统,该系统可以实现对空中及地面目标的被动声定位。讨论了阵列元间距、时间测量精度等因素对定位性能的影响,并进行了仿真。仿真结果表明,该系统消除了目标方位变化对测距和测向精度的影响,具有较好的测距和测向能力。更多还原

【Abstract】 A passive acoustic localization model is put forward based on six element cross arrays.And a moving target or a near ground target localization method has been studied.The various influence factors on localization precise such as array size,time difference measurement etc have been discussed.At the end,the system of acoustic localization is simulated,the result indicated that the measurement error in distance is not dependent on the target azimuth angle.The corresponding algorithm has better distance and direction measuring capability.更多还原
