Measurements and Applications
|
Ocean winds, waves, soil moisture, flooding, ice, snow. Similar to SGR-ReSI-Z, but with a smaller Zynq, and only supports 2 RF channels, only allowing collection of single frequency and single polarisation.

Resolution Summary
|
25 km for diffuse scattering, <1 km resolution for coherent reflections
[Best Resolution: 500m]
|
|
Swath Summary
|
Tracks sampled up to approx 700 km apart, wider possible with different antenna, more channels
[Max Swath: 700 km]
