EcoSAR plane flying over wetlands, forest, or permafrost

EcoSAR is an advanced airborne polarimetric and interferometric P-band (435 MHz) SAR instrument in development at NASA/Goddard Space Flight Center through the 2010 ESTO Instrument Incubator Program (IIP). The aim of EcoSAR is to provide two- and three dimensional fine scale measurements of terrestrial ecosystem structure and biomass.

The system employs a digital beamforming architecture, a highly capable digital waveform generator and receiver system, and advanced dual-polarization array antennas on a P3 aircraft. It is a reconfigurable polarimetric and single-pass interferometric P-band SAR instrument capable of accurately characterizing ecosystems structure and quantify biomass.

P-Band polarimetric backscatter provides the unique capability of mapping the forest cover, disturbance from deforestation and degradation, forest recovery, wetland inundation, and aboveground biomass. P-Band SAR (0.3 - 1 GHz or 30 - 100 cm wavelength) measures forest biomass directly up to 200 Mg/ha (Megagrams per hectare) because of the longer wavelengths and deeper penetration into the canopy. The longer P band wavelength of is also desirable for several critically important science measurements such as permafrost and ice dynamics, in addition to archaeological applications.
