- Abstract
Aiming at the needs of wind turbine clutter (WTC) suppression in passive radar, the modulation model of the wind turbine acting on the radiation signal is built firstly. Secondly, the similar characteristics between the modulation effect of the wind turbine blade and the periodic structure of the radar emission signal on the range Doppler (RD) spectrum is studied・ Thirdly, based on the perspective of periodic component suppression, this paper proposes a new method to suppress the extended Doppler clutter in matched filter processing with the modified reference signal. Finally, simulation test and experimental data are used to analysis verify the proposed algorithm along mith measured data of wind turbine based on passive radar. It shows that this method can improve the effect of WTC suppression, and it has high computational efficiency and less resource occupation・ In addition, this method has been verified with the experiment data of self-developed digital television based on passive radar.
