HELICOPTER RADIO-ELECTRONIC COMPLEX FOR MONITORING AGRICULTURAL LANDS Russian patent published in 2019 - IPC G01V3/16 

FIELD: agriculture.

SUBSTANCE: proposed complex relates to agriculture and is intended for subsurface sounding of agricultural land, detecting of sites of infection of agricultural crops, treatment of depressed areas of cultivated lands, as well as for determining locations of radio sources (RS), for example, “black boxes” with alarm, arising from aircraft accidents. Object of the invention is the expansion of functional capabilities of a known technical solution by detecting sites of infection of agricultural crops, treatment of depressed areas of cultivated lands and determining locations of radio sources (RS), for example, “black boxes” with alarm, arising from aircraft accidents. Helicopter radio-electronic complex for monitoring agricultural lands comprises synchronizer 1, transmitters 2.1–2.4, antenna switches 3.1–3.4, transmit-receive antennas 4.1–4.4, receivers 5.1–5.4, processing blocks 6.1–6.4, review sector switch 7, building pulse generator 8, color indicator 9, thermal imaging sensor 10, television sensor 11, receiving unit 12, receiving antennas 13, 14 and 15, RS positioning unit 16, laser 17. RS positioning unit 16 comprises high frequency amplifiers 19–22, high-frequency oscillator 23, mixer 24, intermediate frequency amplifier 25, complex phase-shift keyed signal demodulator 26, multipliers 27, 28, 31–38, 44, narrow-band filters 29, 35–38, 46, phase meters 39, 40, 47, 48, subtraction unit 41, adder 42, delay line 43, phase detector, registration and analysis unit 52.

EFFECT: expansion of functional capabilities of a known technical solution by detecting sites of infection of agricultural crops, treatment of depressed areas of cultivated lands and determining locations of radio sources (RS).
