摘　　要：合成孔径雷达目标识别是雷达数据解译中一个长期研究的难点问题。近年来,基于模型的SAR目标识别方法由于在扩展条件下的识别性能表现良好而备受关注。在联合国内多家研究单位进行攻关的基础上,该文简要阐述了对该问题的初步研究成果及思考。首先从3个方面出发梳理了散射部件模型发展的技术脉络并对其进行了补充完善;然后从正向推算和逆向反演两条技术途径提出了复杂目标电磁散射参数化建模方法;最后提出了基于复杂目标电磁散射参数化模型的目标识别新框架。论文最后对基于模型的SAR目标识别下一步研究方向进行了展望。Automatic Target Recognition（ATR）is one of the most difficult problems in Synthetic Aperture Radar（SAR）data interpretation.In recent years,the model-based SAR target recognition method has attracted much attention because of its good performance in the extended operation condition.Based on the research of a few domestic research institutes,this paper briefly introduces the preliminary research results and gives some thoughts about SAR ATR problem.First of all,the development of parametric scattering model are discussed from three aspects.Next,two ways to model the parametric electromagnetic scattering for complex target are put forward.Finally,we propose a new framework for a Three-Dimensional（3D）parametric scattering model based SAR ATR.In the end,the future research direction of model-based SAR target recognition is prospected.
