AIM High-Frequency Radar Concept Design

Programme Reference
Start Date
End Date

This purpose of the study was to develop a high frequency radar to sound the first tens of metres of asteroid regolith and to achieve 3D tomography with metric resolution in order to
- Determine its structure and layering
- Identify geomorphological elements (rocks, boulders, etc.) embedded in the sub surface
- Map the spatial variation its texture
- Derive an estimate of dielectric permittivity of the sub-surface material

This purpose of the phase A study was to:
- Revisit the instrument system analysis
- Optimize instrument design inheriting from WISDOM ExoMars
- Define interfaces and programmatics in the frame of the Asteroid Impact Mission
