摘　　要：针对U/VHF超视距信道传播特性研究需求,利用MATLAB GUIDE工具设计了U/VHF频段超视距信道测试统计软件,开发了生成索引模块、回放模块、滑动绘图模块、状态信息模块和统计模块,以实现信道测试统计软件的用户界面显示、数值统计和结果图表化功能。该软件可对实测数据的单频特性、多径展宽特性和频率相关特性进行统计分析,得出信道的时/频域特性,将其与理论预测结果进行分析比较,可得出在典型信道条件下信道传播特性的参考标准。In view of the requirement of studying U/VHF BLOS channel propagation characteristics, the U/VHF BLOS channel test statistic software is designed by using MATLAB GUIDE to develop index creation module, playback module, sliding mapping module, state information module and statistic module and implement user interface display, value statistics and result charting function of channel test statistic software. This software can perform statistics and analysis for single-frequency characteristic, multi-path sprea-ding characteristic and frequency dependence characteristic to obtain time/frequency domain characteristics of channel. Compared with the theoretical prediction results, the reference standard of channel propagation characteristic in typical channel condition is obtained.
