The ATRAD Atmospheric Boundary Layer Radar Systems BLR12/27 has been specifically designed for wind profiling a localised area at heights between 300 metres and 8 kilometres above ground level. Typical system configurations include a 12kW solid-state transmitter and 27 three-element Yagi antenna array. System frequency is set at factory within the range of 30 – 64 MHz.
The BLR12/27 has many applications, which include:
- Weather forecasting and now-casting
- Atmospheric and meteorological research
- Monitoring atmospheric pollutant dispersal
- Wind profiling for airports and aircraft landing strips
- Rocket launch support
- Special event locations
- Weather balloon launch sites
- Glider and commercial ballooning sites
- Data acquisition and analysis
