Near field parameter estimation of moving sources with recursive expectation maximization algorithm

2006    Cekli, Serap; Cekli, Erdinc; Kabaoglu, Nihat; Cirpan, Hakan Ali

In this paper, maximum likelihood (ML) estimator is proposed for the joint estimation of the direction of arrival (DOA) and range parameters of moving sources in the near-field of the antenna array. ML estimation algorithm is presented for, deterministic signal model. Recursive form of the expectation maximization (REM) algoritm is suggested for the estimation of the near-field parameters because there is not closed form solutions for the maximum likelihood functions. Moreover, simulation results of the suggested algorithm are presented.
