DBSAR is a digital beamforming L-band
Synthetic Aperture Radar (SAR) that will
provide critical information on vegetation
structure needed to estimate vegetation biomass.
Digital beamforming permits the implementation
of non-conventional measurement techniques,
which can overcome fundamental limitations of
conventional radar systems (Krieger et al., 2008;
Yunis et al. 2003) such as increasing the
measurement swath without reducing the
received antenna gain, suppressing ambiguities
or localized interference in the receiver signal
and synthesizing multiple beams on both sides of
the aircraft using a single nadir-looking antenna
(Rincon et al.; 2011A, 2011B, 2010).
