Sentences with phrase «radar reflectivity»

Radar reflectivity refers to how well an object reflects radar waves. It measures how much of the radar signal is bounced back to the radar system after hitting an object. High radar reflectivity means the object reflects a lot of radar waves, while low radar reflectivity means the object reflects fewer waves. This information helps in detecting and analyzing objects such as rain, snow, or even aircraft in weather radar systems. Full definition
