An inverse problem for line and strip sources of electromagnetic field above an imperfectly conducting ground plane

An analytic method of solving the inverse problem of determining the optimal excitation of line and strip sources of electromagnetic fields generating given directional functions above an imperfectly conducting ground plane is presented. The method used is based upon algebraization of the problem. The overdetermined system of equations obtained is solved by the method of generalized matrix inverse and the method of regularization of Tikhonov. An error estimate, criteria for the choice of parameters, and an experimental procedure are given. Numerical examples related to airborne radionavigation illustrate the application of the theory.
