Claim 16:
17. A method for measuring attenuation of an irregular surface of a device under test, comprising:
positioning a reference reflector in front of a three dimensional imaging system that uses electromagnetic signals in the frequency range of a radar system;
taking a reference image of the reference reflector by using the imaging system;
positioning the device under test and the reference reflector in front of the imaging system so that the device under test is arranged between the reference reflector and the imaging system;
taking a measurement image of the reference reflector while the device under test is arranged between the imaging system and the reference reflector by using the imaging system; and
comparing the images taken to determine the attenuation of the device under test.
