METHOD FOR DETERMINING TYPES OF RADAR SIGNALS IN AUTOCORRELATION RECEIVER Russian patent published in 2019 - IPC G01S7/40 

FIELD: radio equipment.

SUBSTANCE: invention relates to the field of radio engineering, in particular, to methods and techniques of radio engineering monitoring of radio emission sources (RES). Received signal is filtered, delayed for a specified time, multiply the signal with its delayed copy, a component is allocated at the difference frequency, the amplitude-frequency spectrum (AFS) of the signal is received and the type of the radar signal is determined, additionally after multiplying the received signal with delayed copy thereof, a low-frequency component is extracted and AFS thereof is received, the frequency of the received signal is doubled after filtering, the signal at the double frequency is delayed for a specified time, multiplied with a delayed copy, a low-frequency component and a component at the difference frequency are selected, AFS thereof is obtained, the obtained signal spectra are compared with the specified threshold values and the type of radar signal is determined according to the comparison results, this provides procedures for obtaining and analyzing the AFS of the low-frequency component and the component at the difference frequency of the resulting signal, as well as similar signal components at the double frequency.

EFFECT: expansion of types of radar signals monitored during radio monitoring.
