Description

technical field

[0001] The invention belongs to the technical field of electromagnetic pulse protection, in particular to a high-altitude nuclear electromagnetic pulse protection device for short-wave radio stations. Background technique

[0002] Strong electromagnetic pulses will form surge currents in short-wave, ultra-short-wave and communication equipment. The rising edge time is about nanoseconds, the pulse duration can reach hundreds of nanoseconds, and the radiation field strength can reach hundreds of kilovolts / meter. , the existing lightning protection facilities cannot achieve such a response speed, causing huge damage to the equipment, especially the coupling into the receiver through the antenna is the most harmful.

[0003] Because the effect of high-altitude nuclear electromagnetic pulse (HEMP) environment on short-wave radio stations is more serious than that of conventional electronic countermeasures, and even causes permanent damage to equipment, this puts f...
