CEOS Instrument: X-band Synthetic Aperature Radar




Instrument:Severjanin
Agency: ROSHYDROMET
Missions: Meteor-M N1
 Meteor-M N2
Status:Operational
Type:Imaging radar (SAR)
Description:
Spatial Resolution: 500 m and 1000 m
Swath Width: N/A
Wavebands: X-band
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.
