| 摘 要： | 对直升机等低空飞行目标的无源声测定位与跟踪是声学监视系统的重要研究内容。对多基阵低空飞行目标的无源声测定位方法进行了研究,并导出了定位算法和定位误差。理论分析和仿真实验表明,利用单基阵的方位和俯仰角进行多基阵融合定位时,无源声测定位系统有较高的定位精度,而且布阵形式对定位精度有一定的影响。该研究成果可直接用于对空中运动目标,如无人机等目标的无源声测定位。

| Abstract: | Passive localization the target flying in the air using acoustic measurement is an important aspect of the acoustic surveillance network.Based on the acoustic passive localization with single array,the method of acoustic passive localization with multiple arrays is studied,and the algorithm and its performance analysis are also given in the paper.The method involves bearing of the target that can be gained from the individual arrays.Performance analysis and simulation show that based on the data fusion the multiple arrays'localization performance using bearing gaining from individual array is superior to others,and array shape also contributes to the localization performance.The results could be directly utilized in localizing the target in the air such as helicopters,and so on. |
