Prediction Method for Incident Angle Characteristics of Bistatic RCS of Reflectarray

This paper presents the prediction method of bistatic radar cross section (RCS) of reflectarray. The reflectarrays have been gained attention to reduce the coverage holes for 5G. To evaluate received power from the reflectarray, bistatic RCS of incident angle is required. The Bistatic RCS of incident angle characteristics can be measured by changing the transmitter position, however, it is time consuming. This paper proposes to prediction method to reduce measurement time by the calculation process of near field and far field transformation.
