Aiming at the diffraction effect of wind drive generator to electromagnetic wave,a calculation model of wind drive generator diffraction estimation is proposed,which is suitable for finite-width shielded diffraction loss calculation. The esti-mated value of wind drive generator diffraction loss is obtained through the loss estimation method of the Single knife-edge obsta-cle diffraction and finite-width shielded diffraction,and the simulating calculation is conducted. It is indicated that the wind drive generator in radar coverage sector can cause the improvement of false-detecting and leaking-detecting probability.
