| 摘 要： | 四元十字阵的测向和测距精度受目标方位角的影响，而五元十字阵就可以克服这一缺点。文中研究了基于五元十字阵的低空目标被动声定位算法及其性能。分别就目标测向和测距的精度进行了理论分析和计算．讨论了阵列尺寸和时延估计等诸因素对五元十字阵定位性能的影响。对空中运动目标被动声定位的实际工程应用有重要的参考意义。

| Abstract: | The accuracy of angle and range estimation of acoustic localization method based on four-element sensor array is influenced by target azimuth angle. However, the five-element array based acoustic method do not has this weakness. In this paper, the target localization method based on five-element acoustic array is investigated, the localization equations are derived, followed by the performance analyses. The research results are helpful for the acoustic array system design in the practical applications. |
