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.
