Modeling and Analysis of Wind Turbine Clutter for Metric-Band Bistatic Radar

The clutter generated by wind turbine rotation is difficult to be suppressed by conventional radar clutter suppression methods, which seriously affects the detection performance of radar. Wind turbine clutter modeling is the vital basis of clutter analysis and suppression. Aiming at the metric-band bistatic radar system, the azimuth and pitch angles between the transmitter, receiver and the wind turbine are considered in this paper. The scattering point integral algorithm is used to model the wind turbine clutter. The clutter characteristics are studied through simulation from three aspects: time domain, frequency domain and time-frequency domain. The clutter distribution at different speeds of wind turbine and different wavelengths of radar is also analyzed, which provides a theoretical basis for clutter suppression.
