Abstract :
High resolution and potentially jamming-resistant Synthetic Aperture Radar (SAR) system is presented based on UWB-OFDM architecture. The Omega-K Algorithm (ωKA) is used to construct high resolution SAR image. Suitable waveforms to achieve high resolution SAR image are proposed for both friendly and hostile environments. The proposed waveforms were tested for a point scatterer and for full 2-D SAR image construction.
