near-field source localization in nonhomogeneous environments
source localization is an essential part of array signal processing including radar, sonar, seismology and oceanography applications. the performance of the presented source localization methods are degraded substantially in practical situations. one of the conditions which decreases the performance o
متن کاملSpace-time Matrix Method for Mixed Near-Field and Far-Field Sources Localization
Mixed near-field and far-field sources localization problem has received significant attention recently in some practical applications, such as speaker localization using microphone arrays and guidance systems, etc. This paper presents a novel space-time matrix method to localize mixed nearfield and far-field sources. Using the proposed method, both the direction-of-arrival (DOA) and range of a...
متن کاملPassive Localization of Mixed Far-Field and Near-Field Sources without Estimating the Number of Sources
This paper presents a novel algorithm for the localization of mixed far-field sources (FFSs) and near-field sources (NFSs) without estimating the source number. Firstly, the algorithm decouples the direction-of-arrival (DOA) estimation from the range estimation by exploiting fourth-order spatial-temporal cumulants of the observed data. Based on the joint diagonalization structure of multiple sp...
متن کاملThree-dimensional Localization Algorithm for Mixed Near-field and Far-field Sources Based on Esprit and Music Method
A three-dimensional (3-D) source localization algorithm of joint elevation, azimuth angles and range estimation for the mixed near-field (NF) and far-field (FF) sources is presented in this paper. We first estimate the elevation angles of all mixed sources by using the generalized ESPRIT method. With the elevation angle estimates, the range parameters of all mixed sources are obtained, and then...
متن کاملJRDF Algorithm for Joint Range-DOA-Frequency Estimation of Mixed Near-Field and Far-Field Sources
This paper presents an effective joint range-DOA-frequency (JRDF) estimation method based on fourth-order cumulants for multiple mixed near-field sources and far-field sources impinging on a symmetric uniform linear array, named as JRDF algorithm. Making use of the proposed method, range-DOA-frequency can be effectively estimated by the same eigen-pair of a defined “information matrix” construc...
