摘要
研究了一种基于该方法的分布式麦克风阵列,详细分析了节点测向离散误差产生的原因,仿真分析了该误差对最终定位结果的影响,并提出一种节点优选的建议。仿真结果表明,所述措施能够有效消减定位误差。
This paper studies a distributed microphone array which based on the bearing-crossing locating method. Firstly, it analyses the cause of the discrete bearing measurement errors in detail, and the influence on the final result of localization. Then, it gives advice on an optimal nodes selection. The simulation shows that these measures can reduce the error effectively.
