摘要:
目前,大多数的DOA(direction of arrival)估计算法是应用在高斯噪声环境下的.随着冲激噪声的应用越来越广泛,利用虚拟阵列变换的方法,解决了在冲激噪声背景下对任意阵列进行DOA估计的问题.该方法将任意阵列虚拟成等距均匀线阵,使其阵列流型具有Vandermonde矩阵形式.然后结合分数低阶矩的特点,利用FLOM-MUSIC算法对来波方向进行有效的估计.经计算机仿真,证明了该方法的有效性.
Abstract:
At present, most of the DOA estimation algorithms are used in the Gaussian noise environment. As the application of impulsive noise has become increasingly widespread, the problems of DOA estimation of an arbitrary array in an impulsive noise environment have been solved by use of virtual array transformation in this paper. An arbitrary array is converted to uniform linear array so that its array flow has the Vandermonde form, and then combining the feature of fractional lower order moment, the DOA of arbitrary array is estimated effectively using FLOM-MUSIC algorithm. Its validity is confirmed by computer simulation.
