Abstract

Abstract

In this paper,A new cumulants-based method for the joint estimations of frequencies and 2D-DOAs of spatial signals are dicussed. After analysing the model of data and the virtual-ESPRIT,the authors use PRO-ESPRIT to estimate the parameters of signals based on VESPA.This method utilized the capability of cumulant of aperture extension and insensitivity to additive colored Gaussian noise.M-i signals can be processed by this method with M sensors without searching procedure. The simulations demonstrate the effectiveness of the method.
