郊区环境下角度扩散特性的实验研究

Experiment research on angular spread characteristics in suburb environment

电子装备试验是在特定场区进行的,其电波传播环境与一般移动通信有较大差别。定义了更能反映试验要求的角度扩散参数并利用定向天线扫描法测量了试验环境下几种典型情况的角度功率谱分布,计算分析了这几种情况下的角度扩散值。通过测量分析可知,不同的试验环境其空域特性差别较大,电子装备试验的进行与结果分析必须依据环境的不同对数据进行相应的处理。

Most tests of electronic equipment are performed in a specific area, and its electric-wave propagation environment is different from mobile communication. This paper defines some angular spread parameters appropriate to the test demand and measure the power azimuth spectrum which is obtained with a slowly rotating narrow beam directional receiver antenna under some representative test environment. Then based on calculation and analysis of the angular spread values, it points out that the distinction of spatial characteristics is obvious under different test environment, and the electronic equipment test must process data according to its environment.
