【摘要】 本文设计了一个体积阵列,该体积阵列的一部分由一个面阵组成,另一部分由均匀线列阵组成,并且线列阵所在直线垂直于面阵所在平面。我们把它置于水池实验室环境下进行了实验,验证了阵列波束形成及一系列信号的方位估计算法。实验证明:在体积阵恒定束宽算法中,Dolph-Chebyshev加权法和空间重采样法频率范围内,波束宽度基本保持恒定。在方位估计算法中,MUSIC方法和Min-norm均有着良好的分辨能力,且在低信噪比下Min-norm方法比MUSIC方法分辨率有着明显的改良。更多还原

【Abstract】 This paper introduces the design of a plain volume array,one part of this volume part is the array of a planar array, and another part is composed by uniform linear array,and linear array is in straight line perpendicular to the surface in the plane array.We put it in the laboratory environment pool,experiment is carried out to verify the beam-forming and a series of the orientation of the estimation algorithm.Experimental results show In the volume constant beamwidth array algorithm, Dolph-Chebyshev weighting method and the space re-sampling frequency range,beam width remained constant,in DOA estimation algorithms,MUSIC and Min-norm method has a good ability to distinguish both,And in the low SNR condition Min-norm method of resolution than the MUSIC method has significantly improved.更多还原
