摘要
Abstract
EMC design purpose of the aircraft antenna system is to ensure that all the airborne equipments work normally without interaction interference. In addition, the design takes into account of the antenna performance and requirements of the antenna engineering installation, so as to meet the normal work of other airborne equipments. The simulation software is adopted to perform the simulation calculation of the electromagnetic compatibility of the antenna system in this paper. A 1:1 aircraft shell was produced to carry out the scale-reduced model simulation testing for the antenna layout. The scheme of the entire aircraft antenna layout was obtained. A conclusion that when the isolation degree is too small. it is supposed that the in teraction interference may occur. The time-shearing and frequency demultiplication were considered in the system level. When more antennas work simultaneously at different frequencies, an additional filter should be put into the periodic line of the system or other measures should be taken to improve the inhibition ability of antenna transmitter in the harmonic and third order intermodulation coefficient.关键词
