    摘要： In accordance with a first aspect of the present disclosure, a communication device is provided, comprising: an ultra-wideband communication unit configured to operate in a first radar mode and in a second radar mode; a distance determination unit configured to determine a distance between the communication device and an external device; a controller configured to switch the ultra-wideband communication unit from the first radar mode into the second radar mode in dependence on the distance determined by the distance determination unit. In accordance with further aspects, another communication device is provided, as well as methods for operating the communication device and other communication device, and a corresponding computer program.

    摘要： According to one arrangement, a radar system (10) includes a plurality of antennas, and a processor (13) configured to drive the antennas. In a case of driving the antennas in a first mode, the processor (13) is configured to cause the antennas to be cooperatively operated, and image an object (10a) based on radar echoes received by the antennas. In a case of driving the antennas in a second mode, the processor (13) is configured to cause a first antenna group (31a) to be cooperatively operated, image the object (10a) based on radar echoes received in the first antenna group (31a), cause a second antenna group (31b) to be cooperatively operated, and image the object (10a) based on radar echoes received in the second antenna group (31b). The second antenna group (31b) is different from the first antenna group (31a).
