RECOMMENDED FIELD OF APPLICATION:

In meteorology.

ADVANTAGES:

High sensitivity, which allows you to measure the characteristics of even thin cloud layers with low density. High temporal and spatial resolution. Real-time measurement of cloud density, cloud particle velocity, precipitation intensity, depolarization coefficient, etc. Long-term autonomous operation in any remote place. Continuous automatic calibration of radar sensitivity.
