本文论证了由平面近场测量确定目标散射特性的原理，导出了具体的计算公式。与其它测量方法相比，该法可以提取出目标散射特性的大量信息。对几种简单的目标模型进行了测量，所得到的背向散射图和不同方向来波照射目标时目标的空间散射图均与理论计算符合良好，说明了方法的正确性和优越性。
This paper demonstrates the principle of determining the scattering characteristics of a target by near-field planar measurement, and derives a specific calculation formula. Compared with other measurement methods, this method can extract a large amount of information about the scattering characteristics of the target. Several simple target models were measured. The obtained backscatter maps and the spatial scatter maps of targets in different directions when the targets were irradiated were in good agreement with the theoretical calculations, which illustrated the correctness and superiority of the proposed method.
