FIELD: radio engineering, radio control while solving problem of latent determination of characteristics of radio emission sources. SUBSTANCE: technical result of invention lies in recognition of signals of radio communication systems when parameters of received signal are not known beforehand. It can be achieved thanks to multistep tuning of parameters of receiving system and digital processing of signals that include adjustment by frequency and band of reception of signal, change of discretization frequency of received signal, formation of context second set of classification criteria and adaptive ( context ) connection of second half of classification tree. EFFECT: recognition of signals of radio communication systems with parameters unknown beforehand. 3 dwg
