半球共形阵列的两种虚拟变换方式性能对比
Performance comparison between two different virtual transformations of the hemisphere conformal array
摘要
Abstract
The spatial steering vector of the conformal array usually does not have a Vandermonde structure , so that some fast high-resolution spatial-spectrum estimation methods which are suitable for uniform linear arrays or plane arrays cannot be directly applied to the conformal arrays . This paper adopts the idea of array manifold interpolation transformation and establishes two different transformation relations from a hemisphere conformal array to a rectangular array and a cross array , respectively . Then we comparatively study the performance of the virtual rectangular array and the virtual cross array on DOA ( Direction of Arrival ) estimation , adaptive beamforming and computational complexity . The applicable conditions of two kinds of virtual arrays are clearly confirmed by theoretical analysis and extensive simulation , and results of this paper can provide a reference for the engineering applications of conformal arrays .关键词
