| titleOfInvention | SOURCE SEPARATION METHOD FOR PARCIMONIOUS SIGNALS |
| abstract | This method of determining the arrival direction, respectively the arrival direction and the polarization, of signals from several radio sources by means of a space-diversity sensor network composed of P reception channels , comprises the following steps: a) calculating (106) the successive Discrete Fourier Transforms of the sampled received signal to obtain a time-frequency P-vector grid of measurements of the cut-out signal in windows; b) on each window (120), b1- calculate (122) the covariance matrix (C), b2- count the sources to identify a monosource or bisources window, b3- determine (124) the largest eigenvalues, and vectors own associates of the matrix; c) discretize the domain of the arrival directions (0); d) generating directional vectors (U) for the discrete arrival directions (0); e) associating (130) the directional vectors (U) with the windows; f) for each set of windows associated with the same directional vector (U), obtaining (140) the filtered directional vector of the corresponding source by calculating the eigenvector associated with the largest eigenvalue of a matrix constructed from the values own and eigenvectors of the covariance matrices (C) of the windows. |
