Abstract
In the case of this radar sensor, a phase shifter is inserted between a microwave generator and an antenna and can be switched over between two phases. A demodulator (DM) demodulates the received reflected signal, which has superimposed on it the microwave signal which originates from the microwave generator. A de-multiplexer (DEMUX) which is connected downstream of the demodulator (DM) separates the two phase-shifted demodulated signals. The measurement result is largely noise-free.
