Integrated Sensing and Communication (ISAC) will be one key feature of future 6G networks, enabling simultaneous communication and radar sensing. The radar sensing geometry of ISAC will be multistatic since that corresponds to the common distributed structure of a mobile communication network. Within this framework, micro-Doppler analysis plays a vital role in classifying targets based on their micromotions, such as rotating propellers, vibration, or moving limbs. However, research on bistatic micro-Doppler effects, particularly in ISAC systems utilizing OFDM waveforms, remains limited.

The Oryx dataset contains radio channel measurements between stationary (ground- and rooftop-mounted) and mobile (UAV- and vehicle-mounted) transceivers in a multi-static setup. A variety of dynamic passive objects were present in the measured scenarios, allowing for verification of radar detection, estimation and tracking algorithms. In addition to the measured channel frequency responses, the position of all radio nodes and passive objects were recorded using high-accuracy GNSS RTK devices.
