Abstract

New developments of frequency synthesizers and digital phase detectors make it possible to produce digital radars with high dynamic range that operate in the frequency domain. These radars are especially well suited for ground-penetrating use. This contribution presents the theoretical basis for frequency domain radars and develops a wavenumber domain-based synthetic aperture radar algorithm for inverting the data. The effect of the propagation medium is taken into account, and experimental results from a subpolar glacier are given.
