Practical Limits for Micro-Doppler Simulation Models in Digital Signal Processing

Wind Turbine Micro-Doppler Prediction Using Unscented Kalman Filter

“…The difficulty of the measurements is mainly due to (1) the unavailability of a suitable location for measuring the reflections from wind turbines (multiple measurements are required for different blade rotations to evaluate the variability of the reflected signal Doppler spectrum), (2) the availability of the signal records with different blade rotation speeds (to evaluate the magnitude of the maximum Doppler shift of the reflected signals), (3) climatic conditions (the functionality of the wind turbines at a given measurement time is not guaranteed in case of moderate wind or no wind), and (4) the high cost of the technical equipment needed for the measurements. Due to all these reasons, we proposed a model of the reflected signals from wind turbines, which is described in detail in [31]- [34]. The model allows the calculation of reflected signals for input parameters, both from the radar system perspective and wind turbine perspective.…”
