摘要:在民航甚高频通信应用场景中,一个管制扇区通常配置多个同频的甚高频收发台站来完善扇区覆盖。合理利用外置比选器的信号信噪比比选功能,可以在管制员与机组通信时自动完成最优收发台站的选择,保证管制通话质量及管制工作连续性。

Abstract: In the civil aviation VHF communication application scenario, a control sector is usually configured with multiple VHF transceiver stations with the same frequency to improve the sector coverage. Reasonable use of the best signal selection function of the external comparator can automatically complete the selection of the optimal transceiver station when the controller communicates with the crew, so as to ensure the quality of control calls and the continuity of control work.

Key words: VHF; best-signal-selection; signal-to-noise voter
