Wind turbine filter for weather radar

The project will investigate the feasibility to implement a wind turbine filter into the signal processor of modernised weather radars.

Wind turbines near or in line-of-sight of a weather radar can have a negative impact on the radar's measurements. For this reason, few wind turbines are currently approved for construction near a weather radar. The goal of this project is to investigate the feasibility of filtering out the wind turbine interference.

The project will investigate the technical feasibility of implementing a wind turbine filter in a modernised weather radar. Raw data from wind-turbine-impacted radar cells will be recorded and analysed. To establish a proof of concept a simple wind turbine filter will be developed and implemented in a radar. The technical limitations of the filter will be investigated.

If the project shows that filters can be implemented a future wind turbine filter, of sufficiently high quality and which does not affect the other data collection, may be implemented in all 12 weather radars in the Swedish radar network.
