METHOD OF CREATING INTENTIONAL ACTIVE SIGNAL-LIKE IMITATION INTERFERENCE TO RADIOELECTRONIC EQUIPMENT Russian patent published in 2019 - IPC G01S7/38 

FIELD: radio engineering; electronics.

SUBSTANCE: invention relates to radio engineering and can be used for suppression of radio-electronic detection means. Technical task of the claimed invention is creation of a method adaptive to any type of input signals, creation of intentional active signal-like imitation interference to radio electronic means with provision of interference signal coherency relative to the received signal, as well as creation of interference of at least four radioelectronic equipments. In the method of creating intentional active signal-like imitation interference to radioelectronic equipment (REE), receiving REE signals in the form of a single-pulse reception by means of a combined panoramic receiver with scanning of the frequency band on the principle of parallel processing in combination with search methods adapted for different types of signals of REE, evaluation of signal characteristics and detection of REE is carried out by identification of the type of REE and verification of target designation stored in the program of parameters of targets of suppressed REE of known types, in the absence of target indications of suppressed REE, presence and measurement of the frequency of a single pulse of the signal is checked and information on the frequency of the input signal is generated in the form of a code of the frequency signal number, which is introduced as target designation into a parameter program. Based on the obtained data, the formation of the interference signal is carried out by processing the received signal such that it is perceived by the suppressed REE not as an interfering signal but as a useful signal containing information on the objects of interest, emission of noise signal in direction to transmitter of suppressed REE is performed in form of reciprocal useful signal. During generation of response signals irradiating REE, priority of suppression of most dangerous signals for REE is recorded in memory and priority of signal maintenance is set.

EFFECT: high efficiency of suppression.
