Direction finding by polarization and concealed ballistic launch position detection

The possibility of simultaneous solution of three interrelated inverse problems was demonstrated: polarization direction finding of a flying ballistic object, determination of its trajectory parameters and simultaneously the coordinates of the start point and the expected fall of the object. Any emitter can be used as a source of illuminating radiation, including a nearby TV broadcasting center. The novelty of the proposed approach for direction finding is the use of the so-called vector antenna, intended to measure simultaneously all three components of the electric field strength vector of the wave reflected by the object at the receiving point. The property of a wave with elliptical polarization is used, namely: the plane of the ellipse of polarization of radiation is strictly orthogonal to the direction of propagation. The simultaneous use of two spaced direction finders allows you to solve the problem of positioning. The solution of all three of these tasks in an automated mode will allow almost instantly issuing target designations to the suppression system of the detected firing position and thereby avoid the protected area from further unauthorized shelling.
