FIELD: radio engineering, communication.;SUBSTANCE: first recognition method, based on probing space by moving an antenna beam pattern on angular coordinates, includes measuring the ratio of the strength of received signals in two different angular directions of the beam pattern, making a decision on detection of signals reflected from a target or synchronous repeater jamming signals, if the value of said ratio is respectively close to the square of the ratio of function values of the beam pattern or to the ratio of function values of the beam pattern. A second recognition method, based on forming a packet of detected signals as a result of probing while moving the beam pattern on angular coordinates, on the strength of the received signal, at a known value of the level of the beam pattern, two packet size values are calculated: based on an assumption that signals reflected from a target are detected on an assumption that synchronous repeater jamming signals are detected; making a decision on detection of signals reflected from a target or synchronous repeater jamming signals, depending on which of the calculated sizes is close to the packet size of the detected signals.;EFFECT: recognising synchronous repeater jamming signals and signals reflected from a target in single-position radar sets.;2 cl, 2 dwg
