Global Navigation Satellite Systems-Reflectometry (GNSSR) is an innovative and promising tool for remote sensing purposes. Several applications have been developed to extract geophysical information of the reflected scene from the measured delay waveforms and Delay-Doppler Maps (DDMs). Recently, techniques have been presented to deconvolve the DDMs to reconstruct the Normalize Radar Cross Section (NRCS) field of the observed area in order to provide added value products for imaging remote sensing. In this paper an effective reconstruction scheme, based on the 2-D Truncated Singular Value Decomposition (TSVD), is proposed and succesfully tested on actual Delay Doppler Maps (DDMs) acquired by TechDemoSat-1 (TDS-1) mission.
