Development of the broadband radar network with high resolution

A small-baseline weather radar network consisting of the Ku-band broadband radars (BBR) for meteorological application has been developed. The BBR is a remarkably high-resolution close-range Doppler radar designed for detecting and analyzing rapidly evolving weather phenomena such as severe thunderstorms, tornadoes, and downbursts, which often cause damage to our lives seriously. A radar network with several BBRs (the BBR network) observes multi-directionally and simultaneously these severe phenomena with high resolution in space and time, and with high accuracy. In this presentation, the concept of the project and the initial observation results of the BBR network are presented.
