| 摘 要： | 通过长期的大气湍流强度测试，总结了所测信道大气湍流强度的日变化规律，即测试日下午7:00~次日上午8:00时段湍流最弱，湍流强度约为10-15m-2/3；下午1:00~2:00时段湍流最强，湍流强度约为10-13m-2/3。另外还分析了仪器测试原理，推导了湍流强度与大气温度结构常数、大气温度测试精度的关系，并对实验测试误差进行了评估，为研究大气湍流对无线光通信系统的影响提供了基础数据支持。

| Abstract: | The atmospheric turbulence's daily characteristic is concluded by a long term experimental study, which can be drawn as: the measured turbulence strength is usually week from 7 p.m. to 8 a.m. on the order of 10-15m-2/3, but it is always strong from 1 p.m. to 2 p.m. on the order of 10-13m-2/3. In addition, the test principle of instrument is analyzed. The relationship between turbulence strength and atmospheric temperature structure function and measurement precision is derived to evaluate the experimental result. This research provides fundamental data for atmospheric turbulence research on the optics wireless communication system. |
