DEVICE FOR IDENTIFICATION OF RADIO SIGNALS Russian patent published in 2009 - IPC H04B1/16 G01R23/00 

FIELD: physics, radio engineering.

SUBSTANCE: invention is related to the field of processing and identification of radio signals and may be used in radio engineering devices for detection and identification of amplitude-modulated (AM), amplitude-manipulated (AMn), frequency-modulated (FM), frequency-manipulated (FMn) radio signals, and also radio signals with linear frequency modulation (LFM), with quadratic frequency modulation (QPM) and multiple phase manipulation (PMn). In available device that comprises frequency detector, analysers of spontaneous spectrum, amplitude detector, clipping unit, comparison units, analog-code transducers, unit of logical processing, which includes inverters and logical elements AND, additionally devices are introduced for compression of input radio signal spectrum within the phase changer by 90 degrees, differentiating elements and phase multipliers by two, four and eight.

EFFECT: wider class of identified signals due to identification of complex radio signals with multiple phase manipulation.
