RADIO RECEPTION PROTECTION DEVICE UNDER CONDITIONS OF COMPLEX ELECTROMAGNETIC ENVIRONMENT OF SHIP Russian patent published in 2020 - IPC H04B1/10 

FIELD: electro-radio engineering.

SUBSTANCE: invention relates to electrical and radio engineering and can be used for protection of receiving radioelectronic equipment against powerful electromagnetic radiation. Radio reception protection device comprises a signal analysis unit (2) and a protection option selection unit (3) connected to the antenna, as well as protection units from powerful close-lying emitters (4), from electromagnetic fields of thunderstorm activity (5), from sequence of powerful electromagnetic pulses, repeatedly repeating (6) connected to corresponding outputs of protection option selection unit, and switch of receiving device (7), output of which is connected to input of radio receiving device (8), each input of which is connected to output of corresponding protection unit, and the control inputs of the switch are connected to corresponding other outputs of the protection option selection unit.

EFFECT: technical result is providing stable operation of transceiving radioelectronic equipment from closely located powerful emitters, from electromagnetic fields of thunderstorm activity and from sequence of powerful electromagnetic pulses, repeatedly repeating, wherein each of them has steep leading front of nano- and subnanosecond duration under conditions of complex electromagnetic environment of ship.
