Information Content of Multi-Spectral POLINSAR Data

To quantify added value of the multi-frequency Polarimetric Interferometric Synthetic Aperture Radar (POLINSAR) signatures to learn the bio-/geo- physical parameters of interest  

This activity aims to identify and evaluate any synergies between measurements at different frequencies to improve the estimations of bio and geo physical parameters.   The benefit should be assessed with respect to: The differences and similarities depending on the measurement configuration ? Spaceborne SAR missions operate in very different configurations: single-, dual- or quad-polarimetric or in a mono- or bi- static mode. The performed measurements have different spatial resolutions under different geometries. Feasibility of using established similarities to improve single frequency applications and develop new ones by combining SAR measurements at different frequencies to improve performance of quantitative inversion models Achieved performance after projecting the model inversion performance into different multi-frequency measurement configuration scenarios constrained by realistic implementation and performance figures.   The activity will cover six different areas: quantitative agriculture parameter estimation quantitative forest parameter estimation land cover classification land ice sea ice snow.   This activity encompasses the following tasks: - Document sensitivity of the multi-frequency polinsar signatures - Consolidate multi-wavelength polinsar retrieval schemes for a number of applications supported by appropriate uncertainty analyses; - Demonstrate performance taking into account nuisance factors such as temporal variations of environmental conditions; - Address and identify synergy potential between the different wavelengths.
