Abstract
A method and an apparatus for recognizing an absorptive radome coating on an apparatus for emitting electromagnetic radiation and receiving partial radiation reflected at objects is disclosed. The radome covers at least one antenna of the apparatus. A mixer mixes a frequency-modulated transmission signal with the signal received by the at least one antenna, the mixed product of the mixer is subjected to analog-to-digital conversion, the digitized signal is transformed into a two-dimensional spectrum, and the two-dimensional spectrum is mapped with a transfer function. The two-dimensional spectrum that was mapped with the transfer function is correlated with correlation matrices in order to carry out pattern recognition.
