Type:Imaging radar (SAR)
Description:Images of ocean surface and ice sheets

Swath Width: 450 km
Wavebands: Microwave: 3.0 cm
Technology: Imaging radar (SAR)
Description: If radar is used, the problem of diffraction-limited resolution in MW still applies. In this case, however, by analysing range, azimuth and Doppler effect of the (coherent) signals, synthetic aperture can be implemented, and resolutions typically of 10-30 m can be achieved. Several combinations of polarisations in transmission and reception can be implemented. Resolution can be traded-off with swath (e.g. 30 m / 100 km or 150 m / 400 km). Interferometry between views from different passes enable appreciating changes. SAR exploiting different bands (L, S, C, X) emphasise different features. Applicable only in LEO.
