METHOD FOR DETECTION OF OBJECTS IN MONITORED REGION

FIELD: automatic security systems. SUBSTANCE: method involves emission of microwaves towards objects of monitored premises using FM oscillator, reception and processing of these microwaves after their multiple reflection from objects in monitored premises in order to detect alterations from initial position of objects in monitored premises. Said processing involves periodic registration of amplitude-frequency or phase-frequency response of system. This processing runs simultaneously with spectrum of microwave signal and said characteristics. Comparison provides data for detection of intrusion into monitored premises due to alteration of interference pattern of space in monitored premises using results of simultaneous processing. EFFECT: increased sensitivity and probability of detection of objects of different size which move with arbitrary speed in any point inside monitored premises.
