BackForwardInstrument:  ICEYE SAR 

Instrument details
Acronym ICEYE SAR
Full name ICEYE SAR
Purpose High-resolution all-weather multi-purpose imager for ocean, land and ice
Short description X-band SAR, frequency 9.65 GHz, multi-polarisation and variable swath/resolution [see detailed characteristics below]
Background New development
Scanning Technique Side-looking, possible both to left- and right- end (alternatively), swath 5 to 100 km, depending on operation mode - See table
Resolution 1 to 15 m, depending on operation mode - See table
Coverage / Cycle Global coverage in 1 month for the ‘ScanSAR’ mode (if used 50 % of the time). For the full constellation: daily (less by strategiv pointing)
