Description

The system consists of an antenna unit, a main equipment cabinet (including a master control unit and drive unit), a computer system (including host and display), an oscilloscope, and a UPS power supply. The antenna unit is installed outdoors on flat ground or a rooftop platform; all other equipment is housed indoors. Indoor and outdoor units are connected by cable with a maximum separation distance of 30 m, allowing flexible and convenient site deployment.

Application fields

This sophisticated upper-air meteorological radar finds its place in a wealth of practical scenarios across multiple industries.

For routine meteorological work, it stands as a vital piece of equipment at atmospheric observation posts, steadily gathering layered wind, temperature, humidity and pressure data. These real, detailed readings lay a solid foundation for daily weather analysis, accurate forecast setup and timely early warnings against violent weather events.

In the realm of atmospheric scientific research, its exceptional precise tracking and long-distance measuring capabilities come in handy, greatly facilitating studies on atmospheric boundary layers, instrument calibration tests and in-depth exploration of atmospheric movement rules.

When it comes to civil aviation services, it offers solid atmospheric wind field and structural reference data, helping airlines work out reasonable flight routes, adjust flight plans smartly and guarantee overall operational safety at airports and along air routes.

It also lends powerful support to agricultural development. By feeding back high-altitude meteorological changes, it makes it easier to keep an eye on farmland climate conditions, guard crops against harsh weather and issue early alerts for agricultural disasters in good time.

Besides, it supplies essential upper-air weather information to back up flood risk prediction, rainfall trend judgment and scientific watershed management. Meanwhile, it can clearly capture the vertical movement state of the atmosphere, making it convenient for professionals to analyze how air pollutants spread, evaluate ecological changes and swiftly cope with various environmental emergencies.

Why Choose Our Upper-Air Meteorological Radar

Tailored perfectly for automated upper-air meteorological work, this dedicated radar pairs smoothly with digital radiosondes to form a full streamlined observation workflow from balloon takeoff to final data output. Boasting reliable L-band monopulse phase-comparison design, it delivers steady tracking performance with precise 0.08-degree angle accuracy and 20-meter ranging accuracy all through the whole flight path. It boasts all-round hemispherical coverage with complete azimuth and wide elevation range, never losing sight of targets even when balloons fly straight overhead. It seamlessly handles close targets starting right at 100 meters all the way out to 200 kilometers, easily fixing the near-distance blind spot trouble that troubles most traditional radars. Every step including target tracking, data sorting and information output runs fully automatically, greatly easing staff burdens and keeping data quality steady all the time. What's more, its separated indoor and outdoor structure allows flexible installation with long-distance wiring, letting users set it up effortlessly on professional radar towers or ordinary building rooftops for diverse on-site needs.
