Abstract: One radar excitation signal has a first burst duration and a first sampling period. Another radar excitation signal has a second burst duration and a second sampling period. The first sampling period of the first signal is configured for scanning a velocity range and the second sampling period of the second signal is configured for scanning a portion of the velocity range, and the first burst duration is smaller than the second burst duration. The at least two radar excitation signals are embedded into a frame structure for a wireless communications system. At least one radar operation comprising at least one transmission based on the frame structure is performed. In this way the overhead of the radar excitation signals on the air interface of the wireless communications system may be controlled, while supporting a fine velocity resolution and a sufficiently large maximum velocity for a monitored target.
