Abstract

An active radio frequency antenna lightning protection system disclosed in the invention comprises a lightning protection module and a radio frequency signal input module. The radio frequency signal input module is sequentially connected with an electronic switch and a radio frequency signal output module by a feeder line. The lightning protection module is connected with one end of the electronic switch. The other end of the electronic switch is further connected with a control module and a data acquisition module in sequence. The electronic switch, the control module and the data acquisition module are all connected with a power supply. The active radio frequency antenna lightning protection system of the invention solves the problem that the transmission performance of an antenna is reduced due to the influence of an existing lightning protection device on the signal strength of the high-frequency antenna and the received power. A lightning protection method using the lightning protection system used for the active radio frequency antenna effectively prevents the insertion loss and standing-wave ratio influence of the existing lightning protection device on the radio frequency antenna and improves the transmission performance of RF signals, and the protection method is simple and practicable.

Description

technical field [0001] The invention belongs to the technical field of lightning protection equipment, and relates to an active radio frequency antenna lightning protection system. The invention also relates to a lightning protection method for an active radio frequency antenna by using the protection system. Background technique [0002] During the flight, the aircraft will inevitably encounter severe weather such as thunder and lightning. Flying in thunderstorm weather, once struck by lightning, the protruding parts outside the fuselage, such as the receiving or transmitting antenna, are easily disturbed or even damaged by lightning strikes, resulting in loss of function and affecting the normal flight of the aircraft. Lightning surge interference will also be introduced into the aircraft as external equipment is struck by lightning, affecting the damage to aircraft communication systems and other avionics. Therefore, in order to fly normally in harsh environments, it is ...
