Phase Compensation-Based Localization of Mixed Far-Field and Near-Field Sources
نویسندگان
چکیده
For mixed far-field (FF) and near-field (NF) source localization, most existing algorithms are developed for the scenario where number of available data samples ${N}$ is much larger than sensors notation="LaTeX">${M}$ . Different from these methods, this letter attempts to deal with large same order magnitude as To obtain a satisfied performance in such scenario, phase compensation result spike covariance matrix first utilized construct modified spectral function successively realize DOA estimation FF sources. Then, we exploit oblique projection operation extract NF Finally, range sources achieved via two one-dimensional (1-D) searches, reconstructed manifold vector combining used. The effectiveness proposed algorithm demonstrated by computer simulations.

Passive 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...
