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 modelinversion performance into different multi-frequency measurement configuration scenarios constrained by realistic implementation andperformance figures.- The activity will cover six different areas:- quantitative agriculture parameter estimation- quantitativeforest 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.Procurement Policy: C(3) = Activity restricted to SMEs RD Entities.
