RADIO-WAVE METHOD FOR DETECTION AND IDENTIFICATION OF MOVING OBJECTS AND DEVICE THEREFOR Russian patent published in 2017 - IPC G08B13/24 

FIELD: safety.

SUBSTANCE: invention relates to security means and can be used for detection and recognition of moving objects on a secure boundary. Radio-wave method for detection and recognition of moving objects (humans and animals) involves, in order to determine presence of movements of foreign objects, carrying out analysis of electromagnetic field in control zone of radiator, in particular standing wave ratio. Based on two-dimensional space of features of data on amplitude of standing waves and distance to object via a linear discriminant, decision on classification of object detection is made. Device which realises disclosed method for detection and recognition of moving objects comprises a standing wave meter, device for measuring incident and reflected waves, radiator, directional coupler, two amplitude detectors, two low-pass filters, switch, two direct current amplifier, circuit for calculating standing-wave ratio, threshold device, transmitter, power amplifier, amplitude modulator, driving generator, system of determining range, classifier, decision circuit, actuating device.

EFFECT: technical result is achieved by sharing single-position radio-wave detection method and system for determining range with subsequent classification of a moving object based on two features: standing wave ratio and distance from radiator to object.
