MINE DETECTOR Russian patent published in 2012 - IPC G01V3/12 

FIELD: physics.

SUBSTANCE: mine detector has a power supply unit 1, a transmitting unit 2, a transmitting antenna 3, receiving antennae 4 and 5, a receiving unit 6, a thermal imager 7, an amplitude detector 8, a temperature measuring device 9, delay lines 10 and 11, subtracting units 12 and 13, integrating units 14 and 15, dividers 16 and 17, a reference voltage generating unit 18, a reference temperature generating unit 19, comparator units 20 and 21, switches 22, 23, 35 and 36, needle indicators 24 and 25, a strobe generator 26, a stroboscopic converter mixer 27, a correlator 28, a controlled delay unit 29, a multiplier 30, a low-pass filter 31, an optimal control 32, a range detector 33 and a flip-flop 34.

EFFECT: high reliability of detection and identification of subsurface objects, including mines, by excluding the interfering direct radiation of the transmitter and signals reflected from the air-ground boundary surface.
