Ground Based Weather Radar DWSR 8500S
The Long Range Doppler Processing S-Band Weather Radar DWSR 8500S, a Magnetron based (long life) system from the 1998 range of weather radar solutions from the EEC. The radar is comprised of a transmitter/receiver cabinet and a control rack. The radar antenna has a diameter of 4.2 m. The Radar Control Computer (RCC) provides interface to the radar functions such as antenna movement, pulse width and repetition function, BITE information and system status. The Monitoring Station is part of the radar sensor system. It consists of a software system that allows the operator to control the radar function and visualize radar output when performing system maintenance.
Some of the following technical characteristics are provided:
- Includes 'unfolding' processing for unambiguous detection up to 75 m/s
- Includes Extensive clutter suppression to -40 dB minimum
- Antenna: Solid surface parabolic (diameters 3.2 m to 8.2 m)
- Elevation range: -2° to +90°
- Beamwidth up to 0.95° at 45 dB gain (depending on antenna size)
- Dual polarisation techniques built in
