摘要：

In some cases the objects like wind turbines are so large that the far-field condition are not met within the visibility of the object due to the curvature of the earth. Therefor, new ways to compute the reflections of those objects are required. This is similar to the concept of near-field communications, where the far-field gain (the normal definition) has to be replaced by the near-field gain. In some cases, we will even be able to find simple formulas for the worst case RCS in function of the relative size of the object with respect to the wavelength.
