Abstract

A computer simulation of the measurement and data processing operations is used to demonstrate important factors influencing image formation in an ultrawideband (UWB) synthetic aperture radar (SAR). We first summarize the basic operations involved in UWB SAR measurements and processing. Then we present example calculations based on a two point target scene illustrating the effects of sampling, detector approach, noise and propagation loss due to foliage. The output consists of a computer generated scene illustrating the fidelity, contrast and resolution. Results indicate that UWB imagery is feasible under a wide range of operating conditions.
