SALVAGE SYSTEM Russian patent published in 2011 - IPC G01S15/00 

FIELD: salvage operations.

SUBSTANCE: salvage system comprises high-strength gas-impermeable shells, a device for shells filling with gas, a pocket, an evacuated person, an extension, safety arcs, stabilising parachutes, a pyrocartridge and outlet valves. A radio transmitter comprises a transmitting antenna, a driving oscillator, a phase doubler, the first narrow-band filter, phase manipulators, a modelling code generator, a summator, a power amplifier. A control station includes receiving antennas, high-frequency amplifiers, heterodynes, mixers, intermediate frequency amplifiers, multipliers, narrow-band filters, phase doublers, correlators, a phase divider into four, a phase divider into two, threshold units, keys, a frequency metre, phase metres, a phase detector, a calculation unit, a registration unit, frequency detectors, triggers, balance switches.

EFFECT: increased noise immunity and truth in coherent reception and synchronous detection of complex signals with phase manipulation by elimination of reverse operation of the second type.
