Abstract EN
As a method that does not require additional cost, precipitation measurement by microwave links (MLs) has quickly attracted the attention of experts in meteorological, hydrological, and other related fields, of which wet-dry classification by MLs is one of the most important methods.
Considering that existing commercial MLs are usually single-path, single-polarization, or low-frequency MLs, this paper uses the C-band ML and analyzes the variation in the receive signal level (RSL) of the C-band ML under the conditions of no rain, drizzle, light rain, and moderate rain.
The RSL data are analyzed at different time scales by using long short-term memory (LSTM) network techniques, and then the method for distinguishing parts of the precipitation period by using the RSL from low-frequency MLs is proposed and validated.
The results show that wet-dry classification is ideal.
The accuracy on each day was higher than 60%, and some days had accuracies that were even higher than 98%.
MLs below 10 GHz also had the potential to monitor ground rainfall.
This study will broaden the range of available equipment for MLs for precipitation measurement.
