Altimetric Parameter Estimation in Long Coherent Processing by Airborne Delay/Doppler Altimetry Based on Bayesian Learning

The along-track resolution of conventional airborne synthetic aperture radar altimetry (SARAL), where the coherent processing interval (CPI) is the burst length, is not a full resolution due to beam limited. For a fully focused radar altimeter image, a novel airborne SARAL processing algorithm based...
