可利用feko得到回波或根据公式构造回波，基于字典缩放的属性散射中心的参数提取，并重构回波(The echo can be obtained by using FEKO, or the echo can be constructed according to the formula. The parameters of the scattering center of the dictionary are extracted based on the dictionary scaling and

用于计算目标回波信号，散射中心提取，可应用于各种目标(It can be used to calculate target echo signal and extract scattering center. It can be applied to various targets.)

实体目标散射中心提取，并且能实现高进度的提取(Solid target scattering center extraction, and can achieve high progress extraction)
