In its Carbon Cycle research efforts, prioritized by the National Science Foundation Decadal Survey and mandated by the US Congress, NASA is developing an airborne P-band Ecological Synthetic Aperture Radar called EcoSAR. By using polarimetric and interferometric techniques, and a digital beamforming phased-array architecture, EcoSAR will characterize biomass and ecological structure in three dimensions aboard a P-3 aircraft. One of the main components in the EcoSAR instrument development is the 32 channel RF Electronics Unit (REU). The multi-channel solid-state REU design provides amplification, conditioning, blanking, and several calibration schemes to meet EcoSAR's science and engineering requirements. The design, assembly, and testing of the REU is well underway with 16 of 32 channels completed. The remaining channels are nearly finished. The REU, once complete, will be calibrated and integrated with the rest of the system in preparation for EcoSAR's first flight campaign.

“…These new Next Generation Digital Beamforming Synthetic Aperture Radar systems incorporate advanced features including Multiple Input Multiple Output (MIMO) [4][5] [6], smart radar waveforms, waveform diversity [5], wideband operation, and full polarimetry. NASA/GSFC's recent developments of EcoSAR [7][8] and DBSAR-2 [9] [10] are two such systems. These Next Generation DBF SAR instruments were designed to provide high quality data in support of several disciplines in Earth and planetary sciences, and to set a path for future spaceborne and airborne SAR missions.…”

“…The EcoSAR and DBSAR-2 measurements are applicable to a number of science study areas ranging from ecosystem structure, surface and sub-surface topography, soil freeze-thaw, ice sheet composition, glacier depth, and surface water, among many others. In particular, their measurements can provide unique information on vegetation volumes and densities that can be used to map aboveground biomass, forest cover, disturbance from deforestation and degradation, forest recovery, and wetland inundation, helping us quantify carbon release into the atmosphere [7]. The measurements can also provide an efficient way to detect and document the surface expression of thawing permafrost, helping us quantify the spatial extent of thawing and the accelerating rate of CO2 and CH 4 gas fluxes to the atmosphere, helping us improve our understanding of the carbon cycle [11].…”

Advanced Digital Beamforming (DBF) Synthetic Aperture Radar (SAR) technology is an area of research and development pursued at the NASA Goddard Space Flight Center (GSFC). Advanced SAR architectures enhances radar performance and opens a new set of capabilities in radar remote sensing. DBSAR-2 and EcoSAR are two state-of-the-art radar systems recently developed and tested. These new instruments employ multiple input-multiple output (MIMO) architectures characterized by multi-mode operation, software defined waveform generation, digital beamforming, and configurable radar parameters. The instruments have been developed to support several disciplines in Earth and Planetary sciences. This paper describes the radars advanced features and report on the latest SAR processing and calibration efforts.
