DEVICE FOR GENERATING RESPONSE INTERFERENCE TO RADAR STATIONS Russian patent published in 2022 - IPC G01S7/38 H04K3/00 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering in the field of electronic warfare, electronic suppression, is intended for use in systems for protecting ground and air objects from damage by means of radar guidance by electronic suppression of pulse and pulse-Doppler radar stations in an ultra-wide range of previously unknown radio frequencies. The claimed device contains a series-connected low-noise input amplifier, a radio signal processing unit, an output low-noise amplifier and a power supply unit connected to low-noise amplifiers and a radio signal processing unit. An electro-optical converter, an optical divider, a set of fiber-optic delay lines, an optical adder, an optical recirculation unit, an optoelectronic converter, as well as a maintenance and control unit have been introduced into the radio signal processing unit. In this case, the optical recirculation unit consists of a fiber-optic delay line and an optical amplifier connected in series with each other, and a four-port optical splitter.

EFFECT: increase in the efficiency of radar interference in the form of false targets, as well as an expansion of the functionality of creating response pulse interference, in particular, providing the possibility of creating both single and group false targets.
