Abstract:

This paper addresses the issue of how to characterize an antennas performance in a SAR system-particularly in ultra-wide-bandwidth andor ultra-wide-angle UWBIA SAR-based on simple gain-magnitude versus frequency and angle measurements provided in data sheets. We present eight measures of merit. As illustrative examples, we compare an ideal mathematical model to measurements of an actual antenna designed to perform UWBIA SAR over up to 65- degree integration angles and over a 150- to 550-MHz frequency band.
