Airborne Synthetic Aperture Radar (AIRSAR). For the last 20 years, the AIRSAR mission, flown aboard a NASA-owned DC-8, has served as a test bed for synthetic aperture radar (SAR) technology. Over that time, the onboard capabilities have grown to include full polarimetry in three bands, cross-track interferometry, digital elevation models (DEM), and along-track interferometry. In addition, numerous campaigns have acquired important datasets over specific regions of interest to the earth science community. The resultant data is recognized as being of significant value to those requiring high-resolution DEMs, investigating full polarimetry, or contrasting the response of different bands. In addition, the AIRSAR data will serve as an invaluable historic dataset for comparison to future SAR missions using C, L, and P bands.
