Design of a Low-Power Synthetic Aperture Radar System

This paper reports on an ongoing effort for building a high-resolution synthetic aperture radar (SAR) system. In this preliminary design, our system utilizes the linear frequency-modulated continuous wave (LFMCW) concept, and it operates in the S-band. The generic architecture for our system is presented along with a description of the digital SAR processor. Finally, for demonstration purposes, a focused SAR image for a ground-truthed target in St. John's, Newfoundland is provided.
