METHOD OF DETECTING AND IDENTIFYING EXPLOSIVES AND NARCOTIC SUBSTANCES AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC G01N22/00 

FIELD: physics.

SUBSTANCE: proposed method and device relate to the detection of explosives and narcotic substances, in particular to the methods and devices for detecting explosives and narcotic substances in various closed volumes and on the human body in crowded places. The device implementing the proposed method comprises a transmitting-receiving antenna (1), an antenna switch (2), a transmitter (3), a receiver (4), high-frequency amplifiers (5, 21 and 29), an analog-to-digital converter (6) (7), a memory unit (8), a display unit (9), a monitored object (10), a processor (11), a comparison unit (12), a key (13), correlators (14), (22, 30 and 36), multipliers (15, 23, 31 and 37), low-pass filters (16, 24, 32 and 38), extreme regulators (17, 25, 33 and 39), adjustable delay blocks (18, 26, 34 and 40), a range indicator (19), receiving antennas (20 and 28), an elevation angle indicator (35), an orientation angle indicator (41).

EFFECT: increasing the reliability of detecting explosives and narcotic substances placed on the controlled objects, by precise and unambiguous determining the location of the monitored object and its movement in space.
