The design and implementation of MST radar at Wuhan, China

The basic configuration of the Wuhan MST (Mesosphere-Stratosphere-Troposphere) radar, which is currently designed and constructed by School of Electronic Information, Wuhan University, is preliminarily described in this paper. The Wuhan MST radar operates at VHF band preoccupied with the real-time characteristics of turbulence and wind field vector in the height range 1-100km with a high temporal and spatial resolution. The extensive feature of Wuhan MST radar points to the feasibility of low thermosphere if desired. This all solid state, all coherent pulse Doppler radar is the China´s first independently development of MST radar focusing at atmospheric observation. The primary subsystems of the Wuhan MST radar include antenna system, feeder line system, all solid state radar transmitters, digital receivers, beam control system, signal processing system, data processing system, product generating system and user terminal. Advanced radar technologies are used, including high reliability all solid state transmitters, low noise large dynamic range digital receivers, active phased array, high speed digital signal processing and real-time graphic terminals.
