Digital beamforming synthetic aperture radar (DBSAR): Single-pass interferometry for forest structure estimation

Digital Beamforming permits the implementation of non-conventional measurement techniques, which can overcome fundamental limitations of conventional radar systems. In SAR systems, this technique can enable three-dimensional measurements using a single radar platform. A split phase center technique is implemented with NASA´s digital beamforming SAR. The technique has the potential to provide volume structure estimates in tall forests and glaciers using a single radar platform.
