Abstract :
The UPC lidar group is developing a Doppler wind lidar based on the "edge-technique". Such systems use the slope of a high resolution optical filter as frequency discriminator. A laboratory prototype, able to measure the speed of solid targets emitting continuous wave radiation and using a Fabry-Perot interferometer as optical filter, has been built. A tuning control has been included to compensate drifts between the emitted frequency and the filter resonance frequencies in order to assure maximum sensitive measurements. The design of the system and different results concerning the performance of the tuning control system and speed measurements will be presented.
