SIGNAL DETECTOR Russian patent published in 2001 - IPC

FIELD: radio engineering. SUBSTANCE: invention can be used in mix of radars and communication devices functioning under condition of narrow-band non-Gauss noises for detection of weak signals. Well-known device for detection of radio signals with random initial phase incorporating two quadrature phase detectors, phase inverter, two digitizers, two squarers, adder, square-root calculator and threshold unit is supplemented with signal processing unit which selects algorithm of processing of received digital readings and adaptation unit that generates adaptive value of operational threshold of threshold unit on basis of dynamic evaluation of parameters of distribution of noise envelope. EFFECT: enhanced probability of correct detection of weak radio signals against background of narrowband non- Gauss noises, increased noise immunity. 1 dwg
