F-SAR – Recent Upgrades and Campaign Activities

Kurzfassung

The F-SAR instrument represents DLR’s advanced airborne SAR testbed for technology and remote sensing applications. The development of the instrument was triggered by a strong demand for data being simultaneously acquired at different wavelengths and polarizations as well as by the demand for very high range resolution. F-SAR is a modular development utilizing modern hardware and commercial of the shelf components. For the purpose of experiments and operational data acquisition campaigns the system is being installed on board a DLR Dornier DO228 research aircraft. This paper gives an overview of the instrument’s capabilities and performance, based on the multi-frequency and fully polarimetric imagery acquired during campaigns in the last two years. More specifically, campaigns in Greenland in 2015 (ARCTIC) and Gabon in 2016 (AfriSAR) are presented.
