    摘要:

    针对阵列中传感器阵元对声源定位性能的贡献率不同,开展了基于HBT干涉定位的阵列优化研究。首先,根据声场HBT干涉定位原理,建立了八元直线传感阵列的声学定位理论模型。其次,以阵列定位误差在1%以内为目标,对八元直线传感阵列进行拓扑仿真优化,得到5种四元直线传感阵列。最后,通过实验验证,仿真优化得到的5种四元直线传感阵列中有2种阵列的定位误差在1%以内。本文通过对传感阵列拓扑优化的研究,能够降低传感器的个数,且保证对声源的定位性能不变,从而减少了阵列信号处理的复杂性。

    Abstract:

    For the different contribution rate of sensors to sound source positioning, an array optimization research based on HBT interference positioning is carried out in the paper. Firstly, according to the principle of HBT interference positioning, the sound positioning theoretical model of 8-element linear sensor array is established. Secondly, Taking the array positioning error within 1% as the target, the topology simulating optimization of the 8-element linear sensor array has been carried out, and five 4-element linear sensor arrays have been obtained. Finally, the experiment verifies that the positioning error of 2 of the 5 kinds of four-element linear sensor arrays obtained by simulation optimization is within 1%. Finally, the experiment verifies that the positioning errors of two 4-element linear sensor arrays which is from the five obtained from the simulating optimization is within 1%. By studying the topology optimization of sensor array, it can reduce the number of sensors and ensure the same positioning performance of sound source, thus reducing the complexity of array signal processing.
