AB: Two approaches have been used to estimate the vertical stucture of vegetation from InSAR: 1) Use physical models to estimate structural parameters from a set of InSAR observations, with baseline, polarization, or frequency diversity; or 2) apply external calibration to single-observation InSAR. DESDynI will have some baseline and polarization diversity. It will also have lidar and will benefit from calibrations from other missions such as TanDEM-X. DESDynI will therefore be capable of each of the above approaches, as well hybrids involving both approaches. We will show historical and current results of InSAR structure demonstrations of both types, with emphasis on those at L-band, DESDynI's radar frequency. We will propose candidate observation scenarios for DESDynI and use both airborne and spaceborne results to evaluate them. We will highlight the types of observations needed to better specify the performance of the range of possible scenarios. Biomass estimation processes from each scenario will also be described and evaluated.
