摘要
Abstract
The large scale array with thousands of array elements has been widely used for its high gain and narrow beam in the desired directions.The large scale array with a number of elements usually adopts the two-dimension fast Fourier transform(2D-FFT)algorithm to estimate the direction of arrival(DOA). However,the 2D-FFT algorithm is only suitable for the case that the antenna elements arranged in a rectan-gular grid.If the 2D-FFT algorithm is used for the triangular grid array,the gating lobes will occur.To solve this problem,a new method with phase compensation based on 2D-FFT algorithm for DOA estimation of triangular grid array is proposed.Theoretical analysis and computer simulation confirm the effectiveness of the proposed method.关键词
