CEOS Instrument: L-Band Synthetic Aperture Radar

Agency: CONAE
Missions: SAOCOM 1A
Status:Being developed
Type:Imaging radar (SAR)
Description:Land, ocean, emergencies, soil moisture, interferometry, others
Spatial Resolution: 10 x 10 m 100 x 100 m
Swath Width: 20 350 km
Wavebands: L-band (1.275 GHz)
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.
