GY-3B mobile digital weather radar is an on-site emergency response system designed for meteorological departments and troops to perform mobile tasks, which is mainly used to quickly carry out work in place when emergencies occur, and can monitor rain, hail, cloud distance, azimuth, height, movement direction and cloud thickness within 120 kilometers, and provide key information of on-site meteorological decision-making and service in a timely manner; Cooperate with anti-aircraft artillery and rockets to carry out hail prevention, artificial rain or rain enhancement operations and effect test research with high temporal and spatial accuracy.

GY-3B can also be used in county- and city-scale areas (including farms, reservoirs, and small water conservancy basins) as a fixed radar for short-term, near-term and real-time forecasting, with less investment, simple erection, fast cloud and rain information, and immediate meteorological services.

The GY-3B is characterized by its small size and light weight, and can be carried by jeeps, pickups and commercial vehicles. It can be mounted on the roof of the car, in the car, or even moved by hand. The system can be optionally equipped with GPS GPS.

The equipment uses modern radar hardware technology and DSP digital signal processing technology, accurate measurement, stable performance, high reliability, easy operation, power consumption and less failure. Radar uses stereoscopic scanning technology to obtain basic data throughout the day; The variety of digital weather products generated can meet the needs of various applications.
