全固态多普勒天气雷达

Full Solid-State Doppler Weather Radar System

全固态多普勒天气雷达采用固态发射机，可靠性高，维护成本低，发射机体积小，实现天线系统与收发系统的一体化设计，馈线损耗减小。雷达的工作带宽增加，不需要开机预热时间。满足民用航空、气象和科研等部门气象研究与业务运行保障需求。

主要产品有Ka 、X、C、S四个频段

Equipped with solid-state transmitter, full solid-state Doppler weather radar systems features high reliability, low maintenance cost and small transmitter volume. It realizes the integration development for antenna system and receiver system, which reduces feedline system loss. The operation bandwidth of the radar systems are increased and no warm-up time for power on. Full  solid-state Doppler weather radar systems can widely meet the weather research and related operation guarantee requirements of civil aviation, weather department, scientific research, etc.
