METHOD OF DETECTING INITIAL PHASE MODULATION OF PERIODIC SEQUENCE PULSES

摘要

FIELD: radio engineering, communication.;SUBSTANCE: method of detecting initial phase modulation of periodic sequence pulses is based on two-channel processing of input sequence pulses, wherein in each channel, each pulse of the input sequence is multiplied with the corresponding pulse of the reference sequence and the multiplication result is integrated, as well as on comparing output signals of channels, characterised by that the reference pulse sequence is generated by delaying input sequence pulses for the first channel by a time t=T, and for the second channel by a time t=0, where T is the repetition period of input sequence pulses, and initial phase modulation of the periodic sequence pulses is detected if the inequality U_out.1U_out.2 is satisfied, where U_out.1, U_out.2 denote amplitude of output signals of the first and second channels, respectively, for any of two pulses of the sequence.;EFFECT: enabling detection of initial phase modulation of a pulse sequence.;1 dwg
