RECOGNITION OF THE TYPE OF MODULATION OF THE PULSE SEQUENCE IN THE MEANS OF RADIO ENGINEERING CONTROL

Tsarik Dmitry Vladimirovich

An improved algorithm for recognizing the type of modulation of the pulse sequence in radio engineering control (RTC) is proposed, based on the selection of a set of informative features from the input radio signal, which characterizes the law of change in the pulse repetition intervals. The algorithm includes two stages: dividing the input radio signal into categories and deciding on the type of modulation in a certain space of informative features, which makes it possible to generally take into account the uncertainty of the input information and identify multifunctional radiation sources with a pulse repetition period (PRP) that varies in time randomly. It is shown that the proposed features provide recognition of the type of PTP modulation under conditions of distortion of the original sample by random disturbances
