某型机400Hz机通干扰分析

Analysis on 400Hz Interference to Aircraft of Some Type

提出了某型机机通受400Hz电源干扰的问题,简述了干扰的来源及对干扰的测试情况,并用电磁场理论对其进行了理论分析。通过对干扰采取的相应措施,最大限度地改善了机通干扰现象,使飞行通讯联络正常。

This paper raises the 400Hz power interference of the aircraft, des cr ibes its source and detection of the interference, and gives the theoretical ana lysis on it by means of the electromagnetic field theory. The corresponding meas ures are taken to greatly improve the intercom interference phenomena, thus ensu ring the normal communication in flight.
