摘要

摘要: 合成孔径雷达技术经历了二维SAR、二维半SAR(InSAR)、三维SAR，已发展到如今的多维度SAR，取得了巨大的技术成就。该文在简要总结合成孔径雷达及其成像技术发展历程的基础上，提出了全息合成孔径雷达的概念并首次给出了明确的定义，指出该定义与现有全息雷达、多基线圆迹SAR、多维度SAR等概念的区别与联系。并且基于现有多维度SAR模型框架，给出了全息SAR的成像体制和信号模型，提出了初步的成像思路，为全息SAR技术的发展提供了初步的理论和技术框架基础。

Abstract: Synthetic Aperture Radar (SAR) technology has undergone two-dimensional, two-and-a-half-dimensional, and three-dimensional SAR. It has also developed to multidimensional SAR and has made great technical achievements. After a brief summary of the development of SAR and its imaging technology, this study proposes the concept of holographic SAR and gives a clear definition of the concept for the first time. Furthermore, it points out the difference and connection between this holographic SAR definition and existing concepts, such as holographic radar, circular tomographic SAR, and multidimensional SAR. On this basis, the imaging system and signal model of holographic SAR are established under the framework of the existing multidimensional SAR, and preliminary imaging ideas are proposed. Thus, a preliminary theoretical and technical framework for the development of holographic SAR technology is provided.
