建立基于甚高频无线电波传波路径损耗的通信距离计算模型，对某型飞机在滑跑试验时出现的甚高频通信距离不足的问题进行分析，确定其主要原因是机载电台的接收灵敏度不足和静噪门限值设置偏高，并对甚高频通信系统的设计提出一些建议。

A VHF communication distance calculation model based on radio wave propagation path loss was established and used to analyze the problem of too short VHF ground-to-ground communication distance of a newly developed aircraft. The pri-mary reason was successfully determined to be the too low receiver sensitivity and too high squelch threshold of the airborne VHF transceiver. The problem was resolved by improving the receiver sensitivity design and some suggestions for VHF system design were made at the end.
