Scanning of Random Fields using Blind Source Separation
A method for the measurement of the field generated by multiple non-correlated sources is proposed. The contribution of each source is determined using a blind source separation (BSS) technique. The measurements are performed using one scanning probe and stationary reference probes, avoiding the need to measure the spatial correlations of the random field. The resolving result can be used to localize the emission sources and their contribution to the far-field pattern. The method was tested on different signals with amplitude and frequency modulation.
