X/L-band SAR on Lufttransport’s Dornier DO-228 (LN-LYR)

Current climate changes as well as an increased marine activity in the arctic regions impose a growing need for improved scientific observations and increased situational awareness. This document describes mission requirements for an L- and X-band synthetic aperture radar (SAR), to be installed on the Lufttransport Dornier DO-228 (LN-LYR). An airborne, fully polarimetric, dual frequency, interferometrically capable SAR, would provide a unique platform for regular scientificobservations in the Arctic, in synergy with the existing hyperspectral imager, and the existing land-based infrastructure inSvalbard. An airborne imaging radar would furthermore provide all weather capability with unprecedented potential toimprove observations of vessels, oil spills, icebergs, sea ice conditions, and floating debris. This will lead to improved safety and emergency response in the Arctic and increase the operational window for collecting situational awareness data.
