Prediction of Wind Turbine's Doppler Frequency Shifts

Abstract

This article deals with the prediction of the dominant Doppler frequency shifts of the wind turbine blades. Spread-spectrum of the Doppler frequency shifts of wind turbine blades can mask the radar targets. Current filtering methods are designed to filter only the complete radar resolution cells in places where wind turbines are located. However, these methods do not solve the problem of masking the target. The parametric model was designed to generate the dominant Doppler frequency shifts of wind turbine blades. The non-linear regression model was used for the initial prediction of the dominant Doppler frequency shifts. The prediction model was applied to generated and measured radar data.
