Abstract :
This paper reports on the design and implementation of a high resolution low-power synthetic aperture radar (SAR). Our system utilizes the linear frequency-modulated continuous wave (LFMCW) concept, and it operates in the S-band. The generic architecture for our design is presented along with a description of the digital SAR processor. Finally, for demonstration purposes, a focused SAR image for a ground-truthed target is provided.
