【摘要】 为了检验矢量阵MUSIC空间谱方位估计算法的性能,进行了三元矢量阵的外场试验,对比了MUSIC空间谱估计以及常规波束形成的性能。实验结果表明,相对于矢量阵常规波束形成技术,MUSIC空间谱对目标的方位估计性能得到很大提高。而且,当空间严重降采样时, MUSIC空间谱表现出较强的栅瓣抑制能力,能够在全空间范围内对目标无模糊定向。更多还原

【Abstract】 A lake trial of three-element vector hydrophone linear array was carried out to test the validity and practicability of MUSIC algorithm.Experimental results show that the performance of DOA estimation using MUSIC spatial spectrum is improved comparing with that using conventional beamforming.The sidelobes of MUSIC spatial spectrum are depressed and the right angle estimation are given by the MUSIC spectrum is free from the effect of the undersampled wavefield.更多还原
