| 摘 要： | 本文对高斯白噪声环境下基于L型阵列二维测向的ESPRIT算法进行了改进.该算法利用阵列结构特点通过平滑原理获得3个互相关矩阵,然后由3个矩阵构造一个特殊大矩阵并对其进行奇异值分解来估计信号子空间,最后利用2D-ESPRIT方法实现二维测向.该算法估计精度高,运算量小,能够对相干信号进行估计.

| Abstract: | Based on an L-shape array,a method for estimating two-dimensional direction of arrival (DOA) is developed.The algorithm uses array geometrics to get three covariance matrixes via smoothing theory,and then a special big matrix is constructed by the three covariance matrixes,which is used to estimate the signal subspace.The DOA can be estimated according to the 2-D ESPRIT method.This algorithm is characterized by high precision and low computation cost,and also can estimate the coherent signals. |
