Abstract :
VHF/UHF UWB SAR signal is different from traditional narrow band high frequency SAR in that it has its own special properties. A signal model is derived based on these properties of target and clutter. Several target detectors are available in the literature. A new combined detector is provided which carries on the change detection and the two-parameter CFAR detection in two steps. Our simulation results have shown that the combined detector is simple with significant clutter suppression
