针对风力发电机对电磁波产生的绕射效应,提出风力发电机绕射估算适用有限宽度屏蔽的绕射损耗计算模型;通过刀刃形障碍物绕射损耗估算方法和有限宽度的屏蔽绕射损耗估算方法,可以得出风力发电机绕射损耗估算值,并据此进行了仿真计算。计算表明位于雷达覆盖扇区内的风力发电机绕射损耗会导致雷达漏警率和虚警率的提高。

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.
