A study on the application of millimeter-wavelength cloud radar

In recent years, millimeter-wavelength radar plays an important role in radar remote sensing field. In this article, application of this technique is introduced at first. Then the observation of non-precipitating and weak precipitation clouds by this type of radar is compared with those obtained by X-Band weather radar. The comparison shows that millimeter-wavelength cloud radar is a better way in both the macroscopic and microscopic investigation of clouds. However, this technique undergoes serious rain attenuation which is also introduced in the article.
