METHOD AND DEVICE FOR GENERATING ADAPTIVE RADIO INTERFERENCE Russian patent published in 2019 - IPC H04K3/00 

FIELD: physics.

SUBSTANCE: invention relates to radioelectronic suppression of high-precision weapons control systems and can be used in development of radio countermeasures systems intended for protection of air and ground objects from hitting by self-guided missiles. Method for generating adaptive radio interference, based on detecting an attacking guided missile, determining the fact of guidance of the missile to the protected object and emission of radio interference in the direction towards the missile consists in the fact that they interfere with the missile, the phase coordinates of the missile are measured, using the measured phase coordinates of the missile, the transient characteristic of the missile guidance loop is calculated by the instantaneous miss and its parameters at the extremum point, using parameters of the point of extremum of the transient characteristic of the missile guidance system by the instant miss, determining parameters required for simulating the missile guidance circuit, by mathematical simulation in compressed time scale using mathematical model of missile guidance circuit, parameters of which are refined, calculating relationship of instantaneous miss of missile for each of available types of interferences and selecting type of interference, which provides maximum instant miss of missile, emit interference of selected type in direction towards attacking rocket. In use, the method can reduce the probability of hitting the protected objects to level of 0.1 or less.

EFFECT: technical result is high efficiency of suppression of guidance systems of guided missiles due to adaptive selection of type and parameters of interference, which takes into account parameters of guidance loop of precisely that guided missile, which attacks protected object at current moment in real time scale.
