FIELD: low-level radiolocation, detection of hovering targets and targets flying at low speed against background of local objects and passive jamming. SUBSTANCE: achievable technical result of invention lies in increased authenticity of detection of flying targets against background of passive jamming with maximum employment of methods and means used in present-day monopulse radiolocation. Material component of signal in summing channel of converter is found under mode of search for target. Apart from this phase of high-frequency signal is analyzed in summing channel of converter to find if low- frequency phase modulation is present in signal. Conclusion on detection of target is made after analysis of obtained results. EFFECT: increased authenticity of detection of flying targets against background of passive jamming. 3 dwg
