Abstract (en)
[origin: WO0123906A1] According to the inventive method, the distance from at least one test object (MO) is measured using a CW microwave sensor (MS). The invention is characterized in that at least one active reflector (AR) is fixed to the at least one test object (MO). Said active reflector is used to receive, modulate and emit a signal sent by the CW microwave sensor (MS, RS).
