Virtual Antenna Array Theory and Applications

In this article we would like to present a physical basis of virtual antenna array method which is based on electrodynamic principle of field source equivalence. Also, here are formulae and numerical relations for field description errors for the field at the edges of physical and virtual antenna arrays It is also demonstrated that the virtual antenna array method helps increase radio emitters angular coordinates accuracy even without data about antenna array carrier body geometry and material properties. Potential use of this method is also provided.
