Abstract

Embodiments of the present disclosure relate to a method of testing a radio frequency (RF) attenuation of a radar cover. A radiation detector is provided. The radiation detector is located with respect to a radar device and/or a radar cover at a distance. A reference value of radiated power is obtained. A radar signal radiated by the radar device is received by the radiation detector. A radiated power is determined based on the radar signal received. Information about the radio frequency attenuation of the radar cover is derived from the radiated power by using the reference value. Further, a radiation detector and a test system are described.
