FIELD: radio engineering, in particular, analysis of electromagnetic environment, reconnaissance and suppression of radio emissions, including those with pseudorandom frequency alternations. SUBSTANCE: method involves selection with respect to direction of signal, selection with respect to signal level, selection with respect to frequency jumps. Device provides serial-parallel search of signal by frequency using two channels with different beam patterns of receiving antennas. Selection with respect to bearing is based by comparison of signals from outputs of said channels. Clock synchronization is done by trailing edge of signal elements. EFFECT: generation of jamming aimed at frequency and moment. 13 dwga
