Meteorological Detecting Radar

Description

Meteorological Detecting Radar is an automatic upper-air meteorological detecting radar for China Meteorological Administration. Working with digital radiosonde GTS1, it can obtain wind direction, wind speed, temperature, air pressure and humidity at various layers from ground to the height of 30km and provide accurate meteorological data for weather stations.
The radar consists of antenna, mainframe box (including main control box and drive box), computer (including host computer and display), oscilloscope and UPS. The antenna is erected on outdoor floor or on flat roof; the other devices are put indoors. The maximum distance between indoor devices and outdoor antenna is 30m, which are connected through cable.

Features

It uses phase-comparison single-route single-pulse technology at L band for the first time and thus provides high sounding precision.
It has functions of radar tracking and monitoring, data recording and processing and automatic preparation of meteorological messages.
It has the function of radio theodolite.
It uses new-type temperature, humidity and pressure sensors and thus provides high sounding quality.
It uses short-distance ranging technology, which makes ranging distance within 100m.

Application fields

Our sounding devices are widely applied across diverse fields. They deliver comprehensive upper-air meteorological data to facilitate weather forecasting and severe weather monitoring for meteorological services, support aviation safety and flight arrangement, assist agricultural meteorological research and crop protection, aid flood prediction and water resource management, as well as monitor pollutant diffusion for environmental protection work.

Why Choose Our Meteorological Sounding Radar

CMA-Commissioned Design - We made this system specifically for the China Meteorological Administration. It was built to meet their tough technical and operational requirements for observing the upper air across the country.
First-in-Class Phase-Comparison Technology - This radar uses a new phase-comparison technology, which is a big deal, especially for the L-band. It helps detect things with a level of accuracy you couldn't get in this frequency range before.
End-to-End Automation - Everything is automated, from tracking with the radar and gathering data to making weather messages. This really cuts down on how much work operators have to do and helps avoid human errors.
High-Precision Close-Range Ranging - It can measure distances very accurately even when things are close, within 100 meters. This means the system is useful for all distances, from things right next to it all the way out to 200 kilometers.
Dual-Function Platform - It's a two-in-one system. On top of working as a sounding radar, it can also act as a radio theodolite. This means you get two different instrument functions in just one piece of equipment.
Wide Environmental Tolerance - This system can handle a lot of different outdoor temperatures, from a very cold −40 °C to a hot +50 °C. So, you can use it in all sorts of climates.
