MULTI-FREQUENCY INBOARD STATION OF ACTIVE INTERFERENCES Russian patent published in 2023 - IPC G01S7/38 H04K3/00 

FIELD: electronic warfare.

SUBSTANCE: used in aircraft electronic protection equipment and in electronic suppression systems. The multi-frequency inboard active interference station additionally contains an adder/splitter, a second and a third noise generators, which are functionally the same as the first one. The noise generators operate each in its own frequency range. The frequency overlap ratio of each noise generator is the same. With the same output power of the power amplifier of each noise generator, a uniform interference power density in frequency is ensured over the entire operating frequency range. The outputs of all interference generators are connected to the antenna-feeder system through an adder/splitter. The adder/splitter is made frequency-selective.

EFFECT: increasing the effectiveness of radar countermeasures due to the possibility of generating a wide range of active interference, increasing the sensitivity and accuracy of the electronic intelligence subsystem.
