CEOS Instrument: Ku and X-band radars (SCLP)




Instrument:Ku and X-band radars (SCLP)
Agency: NASA
Mission: SCLP
Status:Proposed
Type:Imaging radar (SAR)
Description:Snow accumulation for fresh water availability
Spatial Resolution: Spatial resolution of 50 to 100m; 15 day temporal resolution
Swath Width: N/A
Wavebands: N/A
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.
