The theoretical base for localization of electromagnetic sources

Abstract

A presented paper deals with a theoretical base of the localization of electromagnetic sources. There are presented a mathematical model of localization of electromagnetic sources in near-field region and the mathematical model in far-field region. The localization in far-field region is introduced by covariance matrix and the localization in near-field region is introduced by cross-correlation matrix. These concepts are very similar in a mathematical apparatus, but the whole fundamental is completely different. There is shown a model of printed circuit board (PCB) with distributed fully coherent source at 1050 MHz for next work with mathematical model in near-field region.
