Problems solved by technology
[0002] When the main frequency of the digital transmission station and the voice station are transmitted, they can be connected to the opposite station through the antenna coupling, which will cause the front end of the receiver to be sensitive and cause interference, which will affect the normal operation of the station.
[0003] In the prior art, the optimized layout of radio antennas cannot solve the problem of mutual interference between radio stations when the main frequency is transmitted.

The invention discloses a radio interference prevention system for aircrafts. The radio interference prevention system for aircrafts comprises a first radio frequency compatible device, which comprises a first sampling input interface, a first data transmission interface, a first output end and a first data transmission output interface; the first sampling input interface is connected with a datatransmission device; the first data transmission interface is connected with a voice transmission antenna; the first data transmission output interface is connected with a voice device; the first output end is connected with a data transmission antenna; a second radio frequency compatible device, which comprises a second sampling input interface, a second data transmission interface, a second output end and a second data transmission output interface; the second sampling input interface is connected with the voice device; the second data transmission interface is connected with the data transmission antenna; the second data transmission output interface is connected with the data transmission device; and the second output end is connected with the voice transmission antenna. The radio interference prevention system for aircrafts disclosed by the invention counteracts the mutual interference by using a mutual signal filtering manner.
Description
technical field [0001] The invention relates to the technical field of electromagnetic compatibility of airborne equipment, in particular to an aircraft radio interference prevention system. Background technique [0002] When the main frequency of the digital transmission station and the voice station are transmitted, they can be connected to the opposite station through the antenna coupling, which will cause the front end of the receiver to be sensitive and cause interference, which will affect the normal operation of the station. [0003] In the prior art, the optimized layout of radio antennas cannot solve the problem of mutual interference between radio stations when the main frequency is transmitted. [0004] Therefore, it is desirable to have a technical solution to overcome or at least alleviate at least one of the above-mentioned drawbacks of the prior art. Contents of the invention [0005] The object of the present invention is to provide an aircraft anti-jammin...
