Abstract: A method of detecting motion by way of a motion detection system comprising a radar apparatus (1) in signal communication with a monitoring and control unit (2), the radar apparatus (1) being configured to generate an electromagnetic signal for illuminating a predetermined monitored space (5); the method comprising the steps of: i) performing (8) at least one scan cycle on the monitored space (5) by means of the radar apparatus (1); (ii) detecting and identifying (9) at least one moving object (6, 7) in the monitored space (5); (iii) locating (10) at least one semi-static zone (S) in the monitored space (5); and (iv) generating (11) an alarm signal only upon detection of at least one moving object (6, 7) in the monitored space, outside the at least one semi-static zone (S).

Abstract: A method and system for identifying an object in one space monitored by at least one radar transceiver. The method comprises storing intervals of critical distance values (10) associated with the position of a fixed object upon which a time-varying radio signal shadow may be generated, which may be confused with a moving object. Through successive radar detections, the signals are processed and generate a measurement range profile (40), from which a background range profile (41) is extracted to obtain an object range profile (50). The distance of a possible detected object (60) is determined from the analysis of the object range profile. If the distance of the object (4) is external to the critical intervals (51), the object is classified as valid (55). If the distance is internal to the intervals, the detected object may be a shadow and unless further checks are performed, its presence is not indicated.

Abstract: A system (1) and a method for finding the direction (?) of a target (6) in a detection plane, e.g. the azimuthal plane. The system comprises a plurality of transceivers (2a, 2b, 2c) which transmit continuous-wave radio signals (4) oriented in distinct main directions of transmission (5a, 5b, 5c) and receive a return radio signal (7) reflected from a target (6), wherein the transceivers have partially overlapping angular fields of view. A controller (9) analyzes the transmitted and return signals by calculating signal amplitudes associated with the return signals and determining the direction (?) of the target as a direction of a mean signal vector obtained from signal vectors having as a modulus the signal amplitudes of respective transceivers.
