In this paper, a time domain stripmap mode Synthetic Aperture Radar (SAR) raw data simulation including both the terrain and the targets is proposed. The simulator generates SAR raw data of a scene, involving both single and double reflections in a computationally efficient manner. The inputs of the simulator are the digital elevation model of the terrain,(More)
In this work, multi frequency continuous wave radar phase unwrapping and the target tracking algorithm are combined. In order to unwrap the wrapped measurement, the unwrapped range measurement or the predicted range is utilized. Methods are assessed with the simulations and field tests. Final tracked range accuracy is shown to be increased without an(More)
Polar Format Algorithm (PFA, is a computationally efficient Spotlight-mode SAR image formation method that achieves high resolution imagery. This method requires that the whole data collected during the aperture time to be stored at the memory. In this paper a method to drive the fundamental steps of the PFA algorithm in real time, the range and azimuth(More)
