Abstract
Synthetic Aperture Radar (SAR) can be used for buried landmine detection from a safe stand-off distance. For a focused SAR image the electrical path length of the electromagnetic wave in soil must be known. In this paper focusing methods for close-in ground penetrating MIMO SAR operated in half-spaces of different permittivity are investigated. The focusing methods are derived from Fermat's principle and are given by an analytical expression using the formula of Ferrari for quartic equations (Ferrari method) and a method which approximates Fermat's principle (iterative method). The focusing methods are verified by simulation and measurement.
