Product Overview
Phased array radar is a radar system that steers its beam by adjusting the phase of the transmitted wave, also known as electronic scanning radar. As a complement to conventional weather radars, it offers advantages such as high resolution and broad coverage, enabling highly detailed weather monitoring. It plays a critical role in detecting low-altitude hazardous weather and severe weather events, as well as in studying precipitation in complex terrain.
