The invention relates to the technical field of electromagnetic compatibility testing, in particular to an airborne ultrashort wave radio electromagnetic compatibility testing system and a testing method thereof. The testing system includes: an anechoic chamber (1), a test aircraft (2), hydraulic pipes (7 ), control room (8), spectrum analyzer (4), control computer (5), etc. The airborne ultrashort wave radio electromagnetic compatibility testing system and the testing method thereof of the present invention can scientifically, comprehensively and more specifically find out the frequency points with hidden dangers of interference, and can be applied in the electromagnetic compatibility mutual interference inspection, so that the aircraft ultrashort wave radio The problem of electromagnetic interference is fully exposed in the engineering development stage, which is more conducive to solving the interference problem of ultrashort wave radio stations in time before the aircraft is delivered for use.
Description
technical field [0001] The invention relates to the technical field of electromagnetic compatibility testing, in particular to an electromagnetic compatibility testing system and testing method for an airborne ultrashort wave radio station. Background technique [0002] In order to pursue advanced mission performance, the aircraft is equipped with various electronic systems and equipment such as communication, navigation, identification, radar, electronic countermeasures, surveillance, reconnaissance, computers, sensors, etc. in a limited space. When the electronic systems and equipment work together , Electromagnetic interference problems often occur. In the process of aircraft development, in order to verify whether the electronic and electrical equipment of the aircraft itself can achieve electromagnetic compatibility, it is necessary to conduct electromagnetic compatibility mutual interference inspection tests for verification. [0003] Among the airborne wireless receiv...
