DVOR副载波上60Hz调幅现象及一种消弱方式的分析

An Analvsis of the AM60Hz on the Subcarrier of DVOR and an Approach to Its Weakening

以理论与实践相结合为出发点，着重分析了ＤＶＯＲ信号副载波上存在着的６０Ｈｚ调幅现象，指出边带天线间的“寄生辐射效应”

Starting from the principle of integrating theory with practice,the paper puts em- phasis on analysing the AM60 Hz on the subcarrier of the DVOR, points out that the 'Parasitic radiation effect' between the side - band antennas is the chief factor detrimental to the quality of the DVOR signals and, centering upon this point, analyses the measures taken and the principles based on to weaken this phenomenon in designing, fixing and debugging the AWA - 51D DVOR.
