Efficient simulation of coupled ground antennas

A novel technique is presented for the accurate and efficient simulation of Ground Penetrating Radar (GPR) antennas coupled to an arbitrary ground. The problem of generating an impedance matrix is reformulated using expressions of the basis and testing function far-field patterns which are independent of the ground´s physical and electromagnetic parameters. This allows for efficient calculation of the antenna´s impedance matrix while looping through values for the soil parameters.
