Abstract
An ultrasonic motion detector exhibits at least one ultrasonic transmitter (S1) and at least two ultrasonic receivers (E1, E2) which are aligned towards a common surveillance area (ÜE). In an associated signal processing and evaluating device (SAE), the distance (e) and direction ( alpha ) of a moving object (OB) is determined by means of a microcomputer ( mu R) from the received echo signals (ES) and from this a motion track is formed, a criterion for alarm signalling (AL) being derived from the length and shape of the motion track. The distance (e) is determined from the transit-time differences and the direction ( alpha ) is determined from the phase differences between the processed echo signals. <IMAGE>
