The European Space Agency Tender

In The Recent Years Technical Progresses In The Analysis Of Products From Radiometers, Altimeters And Synthetic Aperture Radars, Operating In The Frequency Range Between L- And Ka- Band Have Been Achieved In Order To Better Quantify Parameters And Processes That Dominate Earth's Polar Ice-sheets. There Is Now Some Interest In Microwave Sounder Concepts (active Or Passive) For Observing Those Regions. However, One Critical Aspect That Is Often Simplified Is The Complex Nature Of The Deep Internals Of Polar Ice And Its Impact On Microwave Signatures. In Addition, The Low Frequency Region Of The Microwave Spectrum Between Vhf- And L-band - Despite Being Unique In Its Capability Of Probing Deep Into The Ice Layer As Demonstrated By Many Airborne Campaigns And By Planetary Science Missions - Still Needs To Be Investigated, And Its Potential For Space-based Earth Observation Needs To Be Quantitatively Assessed.the Activity Aims At Consolidating Microwave Emission/scattering Solutions For Low Frequency Nadir Sounding Of Ice In Order To Set-up A Reference Framework For Developing Inversion Algorithms. Focus Shall Be On Ensuring Consistency Across The Frequency Range And Active/passive Concepts In Order To Support Synergy Between Missions.this Activity Encompasses The Following Tasks:- Review Of The Ice Sheet Structure And Properties Affecting Low Frequency Microwave Emission And Scattering (from Vhf To L-band)- Consolidation And/ordevelopment And Validation Of New Microwave Emission/scattering Models- Development, Improvement And/or Refinement Of Inversion Algorithms For The Estimation Of Ice Structure Profiles And Ice Temperature- Assessment Of The Performance Of The Inversion Techniques And Of The Potential Synergies Between Observation Conceptsdeliverables Shall Include Algorithmic Description Of The Techniques, Validated Performance Assessment As Well As Software.software Shall Be Delivered Under An Esa Software Community Licence.procurement Policy: C(3) = Activity Restricted To Smes Rd Entities.
