| Abstract | 大气不透明度是大气对射电信号衰减的一个度量，精确的射电信号强度校准需要修正大气的吸收效应。大气不透明度测量方法有数值模拟及非线性拟合等方式。为了在7毫米波段实现高精度的强度校准，进一步学习及实践大气不透明度测试方法，通过组建7毫米波段大气不透明度测量系统，采用俯仰扫描及非线性拟合方式开展7毫米波段大气不透明度测量研究。最终，在30-32 GHz频段内测试到大气不透明度值在0.11-0.13之间。下一步工作拟结合对应波段的地基式测量设备，例如水汽辐射计，对测量到的不透明度进行比对，以便对测试系统进行可靠性验证以及后续完善。 |
| Other Abstract | Atmospheric opacity is a measure of the attenuation of radio signal by the atmosphere. Accurate amplitude calibration of radio signal needs to correct the atmospheric absorption effect. The measurement methods of atmospheric opacity include numerical simulation and nonlinear fitting. In order to achieve high-precision amplitude calibration in 7mm band and further study and practice atmospheric opacity measurement methods, the atmospheric opacity measurement system in 7mm band is established, and the atmospheric opacity measurement in 7mm band is carried out by using elevation scanning and nonlinear fitting. Finally, the atmospheric opacity is between 0.11 and 0.13 in the 30-32 GHz band. The next step is to compare the measured opacity with the ground-based measurement equipment in the corresponding band, such as water vapor radiometer, so as to verify the reliability of the test system and improve it later. |
