Abstract :
Recent advances in wideband digital waveform generation, analog to digital converters (ADC) and high speed parallel processing provide the technology to develop ultra wideband systems for simultaneous synthetic aperture radar (SAR) and ground moving target indication (GMTI) modes. These systems are designed at either VHF or UHF frequencies to minimize the foliage attenuation and clutter masking of either terrain features or objects. The evolving challenge is to develop a common waveform for both SAR and GMTI, with emphasis on real-time signal processing.
