Integrated sensing and communication (ISAC) enables the detection of objects in proximity of base stations or user devices and data communication within the very same technology, namely within 6G. This demonstration shows how to objectively measure sensing performance based on test instruments, which enable object emulation in terms of distance, speed and radar cross section (RCS) in mmWave spectrum. The device under test (DUT) in this demo is provided by the Karlsruhe Institute of Technology (KIT).
