| 摘 要： | 为拓展散射通信在各种地域时域环境下,比如在沙漠、海面、春夏秋冬季及不同天气状况下的应用,需对各种地域、季节和天气状态下对流层散射信道的电波传播特性进行测试和统计。基于USB接口的散射信道测试设备,对信道特性-电平衰落、信号多径传输特性、相关带宽及空间相关性进行单项或多项循环测试。用PC机对测试数据进行图形化显示并对数据完成后续处理与分析,具有连接方便、数据传输速率高、可热插拔等优点。

| Abstract: | To expand the application of troposcatter communications in different environments, such as desert, sea, four seasons and various kinds of weather, the characteristics of radio wave propagation in troposcatter channel are tested in various terrains, seasons and climates. Troposcatter channel test device based on USB interface may test multiple channel characteristics such as fading, multipath, correlation bandwidth and spatial correlation, one by one or in turn circularly. Besides, it has the advantages of easy connection, high-speed data transmission and supporting hot plug, etc. |
