Amine defended his dissertation on the topic "System Concepts for Multistatic UAV-Borne Synthetic Aperture Radar". Congratulations!

Proudly presenting: Our joint paper “Towards Detecting Climate Change Effects With UAV-Borne Imaging Radars” is published. This paper is a cooperation between all KoRaTo groups. It presents the capabilities of UAV-based radar systems and the associated challenges in terms of system design and imaging techniques for detecting and monitoring the effects of climate change.

By distributing radar sensors across multiple UAVs, new applications and improved imaging become possible. But how are the individual sensors synchronized in order to continue using the principle of synthetic aperture (SAR)? In our article, we present a concept in which synchronization is achieved through signal processing, enabling lossless imaging. Published in IEEE Transactions on Radar Systems, available as an early-access article.

Christian Gesell has received the VDI Prize for his master thesis titled "Kohärente bistatische Radarbildgebung mit ungekoppelten Digitalradaren". Congratulations!

We congratulate Marius Widmann on receiving the VDE Prize for his master thesis titled "Signalverarbeitungskonzepte für drohnengestützte SAR-Interferometrie".

A team of KoRaTo Members has sucessfully recorded cryospheric measurement data for the first time. For this campaign, we were in Switzerland and worked at the high-altitude research station Jungfraujoch at 3500m.

Our associated postdoc Ingrid Ullmann received the Best Paper Award at the IEEE SENSORS 2023 in Vienna, Austria. The presented paper, “Radar-Based Continuous Human Activity Recognition with Multi-Label Classification“ is based on a cooperation with the Microwave Sensing, Signals and Systems Group at TU Delft. Ingrid had the opportunity to visit Delft last year (2022) in October during her research stay abroad.

The combination of synthetic aperture radar (SAR) with bistatic measurement geometries creates an opportunity to improve imaging significantly. A repeater element can be used for bistatic imaging to circumvent the need for highly accurate synchronization. The new article in the Journal of Microwaves, authored and co-authored by KoRaTo-Members Alexander Grathwohl and Julian Kanz, shows simultaneous mono- and bistatic SAR imaging with an airborne UAV-based radar system and a stationary repeater element in a practical measurement scenario.
