Abstract : In this paper, two relatively novel Synthetic Aperture Radar (SAR) imaging techniques, namely back-projection algorithm and range migration algorithm, are discussed. The back-projection algorithm originates from the medical imaging reconstruction technique called computer-aided tomography whereas the range migration algorithm is derived from seismic migration techniques. In this paper, both the back-projection and range migration algorithms are applied to FOliage PENetration (FOPEN) SAR imaging and the performance comparisons are made. The simulation and experimental data processing results show that both algorithms are suitable for FOPEN radar imaging and the theoretical performances can be achieved.
