DO-228
Dornier 228

The airborne F-SAR instrument developed by the German Aerospace Center (DLR) was designed as an upgraded implementation of the E-SAR instrument to include multiple wavelengths as well as higher spatial resolutions. The F-SAR instrument contains 5 fully polarimetric wavelengths at the X-, C-, S-, L- and P-bands. It can measure at off-Nadir angles between 22 and 55 degrees at maximum altitudes of 6000m above ground level. The F-SAR currently flies on-board the DO228 aircraft.
