An algorithm for near-field source localization
Xuehui Shao · Applied science and technology · 2007
A joint estimation algorithm for two-dimensional DOA and range of near-field sources was proposed,which used the eigenvalues of a forth-order cumulant matrix to estimate DOA of each source.Then the range estimation was performed with the estimated DOA through finite one-dimensional searching.This algorithm reduces two-dimensional searching to one-dimensional searching,thus improving the precision of range estimation because a high-order cumulant matrix is used.Finally,the effectiveness of the proposed algorithm was verified by computer simulation.
