Rain monitoring through signal attenuation has been a significant concern for the scientific community over the last decade. The lowest L‐, S‐ and C‐bands in the microwave spectrum are full of potential for environmental monitoring devices. It has not been extensively proven whether signal attenuation can be used for rain estimation throughout the microwave spectrum in the region of 1–6 GHz. The study derives a power‐law rain estimation model by validating the one year data for the amount of rain and signal attenuation at the lowest limit of the S‐band. This is achieved by a prototype accurate experimental set‐up in a laboratory environment at the campus of the University of Ioannina, northwest Greece. A comparison with global rain attenuation models as well as measurements near this frequency band are also presented and discussed.

基于微波信号衰减测量的希腊约阿尼纳市雨量估算模型

在过去十年中，通过信号衰减进行雨水监控一直是科学界关注的重大问题。微波频谱中最低的L，S和C波段具有用于环境监测设备的潜力。尚未广泛证明信号衰减是否可用于整个1–6 GHz微波频谱中的降雨估计。这项研究通过验证一年数据以验证S波段最低界限的降雨量和信号衰减量，得出了幂律降雨估算模型。这是通过在希腊西北部约阿尼纳大学校园内的实验室环境中进行精确的原型实验设置来实现的。还介绍并讨论了与全球降雨衰减模型的比较以及该频段附近的测量结果。
