Abstract

In this paper, a simple electromagnetic model for wind turbine's backscattering is proposed. The wind turbine is modeled as a linear structure made of three rotating wires on which an electromagnetic fields impinges. Since a wind turbine is much bigger than typical radar range resolution cells, just a small part of it is involved in the backscattering for a single resolution cell. An analysis of the micro-Doppler features for each range cell involving the wind turbine is then proposed. The models are both compared and validated using real data acquired with PARSAX radar. The main features obtained from these models can be used to understand the backscattering mechanisms for a wind turbine and for developing of clutter mitigation algorithms.
