| 针对我国航空通信中VHF(Very High Frequency)频率资源紧张的现状，提出将信道间隔从25kHz减小到8．33kHz的解决方法。根据对选择连续信道概率的理论分析，提出了减小信道间隔后将同波道类型频点分散到不同频谱，同时设置预留区的规划方案。在规划过程中，考虑抑制干扰和灵活指配等因素，结合现有通信系统台站频率使用情况，对频率资源进行整合，说明将信道间隔减小到8．33kHz是行之有效的方法。 |

| Abstract: |
| Considering the shortage of VHF(Very High Frequency) radio frequencies in aeronautical telecommunication in China, a method of decreasing channel spacing from 25 kHz to 8.33 kHz is presented. According to the analysis of probability of selecting continuous channels, after decreasing channel spacing to 8.33 kHz, the channels of same purpose are divided into different bands, at the same time some frequencies are left to special area. In the process of allocation, thinking about the factors ,like anti-jamming and assigning flexibly, the frequency is assigned on the basis of frequencies used in present communication systems. The method of decreasing channel spacing to 8.33 kHz is proved efficient. |
