Abstract :
This paper compares and analyzes the imaging capability of two ultra-wideband radar systems which are based on synthetic aperture and sparse planar array respectively. The systems comprise the same 3.1-10.6 GHz antennas and video-impulse electronics. The SAR uses a transmit-receive antenna pair installed on 2D mechanical scanner, while the array represents an multiple input multiple output (MIMO) structure with four transmit and sixteen receive antennas. In both systems digital beamforming is applied to the acquired data. The comparison bases on measurements conducted for the same scenarios.
