Abstract

The application belongs to the technical field of electromagnetic compatibility testing of airborne communication radio frequency receiving equipment, and in particular relates to a quantitative index electromagnetic interference testing system and a testing method of airborne communication radio frequency receiving equipment. The test system includes: a radio frequency signal output device, which is used to generate an adjustable radio frequency signal and output the radio frequency signal; the aircraft to be tested includes: airborne communication radio frequency receiving equipment and one or more other airborne equipment, any After other airborne equipment is turned on, it becomes the electromagnetic interference source of the airborne communication radio frequency receiving equipment; the radio frequency signal measurement device; the receiving antenna can receive the radio frequency signal output by the radio frequency signal output device; the receiving antenna has: installation state, the receiving antenna is installed on the airborne On the communication radio frequency receiving equipment; in the measurement state, the receiving antenna is connected with the radio frequency signal measuring device. The test method is based on the above test system, and this method can more scientifically evaluate the performance of aircraft airborne communication radio frequency receiving equipment.

Description

technical field [0001] The application belongs to the technical field of electromagnetic compatibility testing of airborne communication radio frequency receiving equipment, and in particular relates to a quantitative index electromagnetic interference testing system and a testing method of airborne communication radio frequency receiving equipment. Background technique [0002] In the electromagnetic compatibility and mutual interference inspection test of the whole aircraft, because the airborne communication radio frequency receiving equipment is affected by the external electromagnetic environment and the performance of analog signal equipment, although it is possible to know the receiving sensitivity performance index of the radio frequency communication receiving equipment, it is difficult In the electromagnetic compatibility and mutual interference inspection test of the whole machine, the electromagnetic interference problem is quantified. [0003] At present, the el...
