DBSAR
Digital Beamforming Synthetic Aperture Radar

The Digital Beamforming Synthetic Aperture Radar (DBSAR) is an airborne L-band (1.26 GHz) radar system developed at NASA's Goddard Space Flight Center (GSFC). It employs polarimetric and interferometric digital beamforming techniques to capture radar imagery. DBSAR has three operational modes: scatterometer, synthetic aperture radar (SAR), and SAR altimeter. It features a slant range resolution of 7.5 meters and a subarray 3-dB beamwidth of 106 degrees.
