Spatial structure of the phase state of the field generated by a system of closely spaced radiators

Abstract: Questions concerning the phase state of the near field generated by single radiator, as well as systems of such radiators, are discussed. The productivity of the near-field low-frequency multi-view sensing technology is emphasized when solving the tasks of high-precision localization of a single radiator (tag) in conditions of a complexly constructed medium in which radiation is propagated. A method to develop this technology by applying to the tasks of near-field sensing of media and objects of medium resolution is proposed. The basis of this technique is active multi-view sounding systems of closely located radiators. Examples of computer modeling are presented, demonstrating the fundamental capabilities of the technique.
