LY-M1 microrain radar

发布时间:2024-05-16


After years of research and development experiments, our company has successfully developed a domestic small rain measuring radar - LY-M1 micro rain radar, which provides a rain measuring instrument for the research of hydrology and ecological environment.

The principle of microrain radar is based on the relationship between raindrop size and scattering cross section, raindrop size and falling rate. The micro rain radar uses a single phase static antenna structure to reliably measure the raindrop size distribution.
