The Near-Field Scattering of Chaff Cloud

The near field electromagnetic scattering of the chaff cloud is discussed in this paper. The cloud is illuminated by a horn antenna which is located in the near field region of the cloud. The scattered far field is calculated with method of moments which the coupling between chaff elements can be considered. Some simulations are done to analyze how the scattering results are affected by antenna pattern, the distance between the antenna and chaff cloud and the density of the chaff cloud.
