The radar for the UAV platform is a
compact pod-mounted polarimetric L-band
radar for repeat-pass observations.
The system will demonstrate key measurements
— both during and after a seismic
event — for monitoring volcanic activity
and for monitoring anthropogenic induced
surface change such as subsidence induced
by oil or water withdrawal, or other
displacements of the surface from tunneling
activities.
- Polarimetric interferometry, which can provide NASA with measurements of forest structure and sub-canopy topography.
- Polarimetric tomography, mapping in detail the vertical structure of a vegetated area.
Optional later additions to the system might include a second across-track antenna for single-pass interferometry (elevation mapping capability), a second antenna mounted along-track for along-track interferometry (velocity and current measurements), and additional frequencies of operation for expanded science applications
