Abstract
    Up to now, all previous studies have focused on the influence of moving objects such as wind turbines on aeronautical and maritime radars that normally operate in the L/S band or in the X-band respectively. We have used both UTD methods as well as simplified methods to quantize the effects. Not many moment method solvers are capable of dealing with moving objects (creating Doppler shifts) in a fully consistent way, but with UTD it is within easy reach of the modern computers. However, for some particular applications, the procedures can be simplified to quantize efficiently the near-fields around moving objects. After a description of the general phenomena, two simplified methods will be compared. The first consists in a Physical Optics based method and the second makes use of the flat wedge approximation.
