Abstract

In this paper, a novel time-frequency Root-MUSIC method for near-field source localization is proposed. In the method, two spatial time-frequency matrices of Pseudo Wigner-Ville distribution (PWVD) are constructed, and a time-frequency Root-MUSIC algorithm is developed to estimate bearings and ranges of near-field targets. It has high accuracy and resolution for the bearing and range estimation of non-stationary signals, even when the signal-to-noise ratio (SNR) is low, or the sources are closely spaced. The effectivity of the method is validated by simulations.
