FIELD: data processing.
SUBSTANCE: invention relates to digital processing of signals and other industries, in which digital matched filtration (compression) of signals with intrapulse modulation can be used. Result is ensured by using a corrected copy which takes into account features of the frequency-modulated (FM) signal spectrum (Fresnel pulsations), as well as distortion originating in the receiving path.
EFFECT: high efficiency of processing real FM signals, which, as compared to conventional processing, provides the required level of side interference of compressed signals in a given range of Doppler frequencies without increasing the peak duration compared to traditional weight processing.
