FIELD: salvage operations. ^ SUBSTANCE: device for the method realisation comprises a scanning unit and a transceiver. The scanning unit comprises a driving oscillator 1, a power amplifier 2, a circulator 3, a transceiving antenna 4, high-frequency amplifiers 5 and 26, a phase detector 6, a computer 7, a heterodyne 8, mixers 9, 11 and 27, an amplifier 10 of the first intermediate frequency, amplifiers 12 and 28 of the second intermediate frequency, the first 19 and 29 correlators, multipliers 20 and 30, low-pass filters 21 and 31, optimising peak-holding controllers 22 and 32, controlled delay units 23 and 33, a range indicator 24, the second receiving antenna 25, an angle indicator 34, phase doublers 35 and 39, phase dividers into two 36 and 40, low-pass filters 37 and 41, a phase metre 38. The transceiving unit comprises a piezocrystal 13, a microstrip antenna 14, electrodes 15, buses 16 and 17, a set of reflectors 18. ^ EFFECT: increased accuracy of their detection by accurate and unambiguous determination of their azimuth. ^ 2 cl, 3 dwg |
