Dual-Mode Interferometric Experiment Using Ka DBF-SAR

Abstract

Ka-band DBF-SAR can achieve system integration in a light and small way. It can acquire along-track and across-track multi-channel data in one observation. Ka band SAR system have the characteristics of rich details and fine texture representation by its shorter wavelength. It has the advantages of observing metal structure, target shadow and other key target characteristics. Airborne experiments and offline signal processing were taken. Mission highlights includes multi-channel imaging in elevation and dual-mode InSAR. Interferometric information of height and velocity are extracted by the effective baseline in the range and azimuth respectively.
