Abstract
The invention relates to a method for monitoring the integrity of a Doppler transceiver, where a Doppler transceiver comprises a transmitter unit, a receiver unit and a mixer unit, where a signal is transmitted from the transmitter characterized in that the transmitted signal is at least partially coupled into a modulation unit, where the coupled signal is modulated according to certain parameters, and the modulated signal is transmitted to the receiver unit. The invention also relates to a Doppler transceiver comprising a transmitter unit and a receiver unit having at least one antenna (34, 54, 66, 74, 90, 96) and a mixer unit (38, 64), characterized in that it also comprises a modulation unit (48, 70, 86, 106) which is electrically disconnected to the antenna (34, 54, 66, 74, 90, 96).
