RADIO-WAVE DOPPLER DETECTOR Russian patent published in 2017 - IPC G01S13/56 

FIELD: electronics.

SUBSTANCE: invention relates to signals detection and classification equipment, recieved from objects in radio wave (super high frequency UHF range) device. Method of increasing resistance to false triggering in case of animals appearance consists in following: SPDRWD (single-position Doppler radio wave detector) is capable to recognize human and animal by information, contained in UHF signal reflected from object. During reflection signal is modulated and carries information on object. From received signal Doppler component is selected, which is amplified, filtered and supplied to detector. When detecting signal exceeding threshold level, features selection "circuit" is launched. Selection of criteria is obtaining information from signal contained in it during reflection from object. Information is transmitted to decision making "circuit", which according to classification model loaded into it (binary solutions trees set weighted voting) decides on issuing of alarm signal.

EFFECT: technical result is increase in single-position Doppler radio wave detector (SPDRWD) noise-immunity in case of animals appearance in detection zone.
