Geometric object/image relations for radar
D. Gregory Arnold, Kirk Sturtz · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2000
Recent research in invariant theory has determined the fundamental geometric relation between objects and their corresponding 'images.' This relation is independent of the sensor (ex. RADAR) parameters and the transformations of the object. This relationship can be used to extract 3-D models from image sequences. This capability is extremely useful for target recognition, image sequence compression, understanding, indexing, interpolating, and other applications. Object/image relations have been discovered for different sensors by different researchers. This paper presents an intuitive form of the object/image relations for RADAR systems with the goal of enhancing interpretation. This paper presents a high level example of how a 3-D model is constructed directly from RADAR (or SAR) sequences (with or without independent motion). the primary focus is to provide a basic understanding of how this result can be exploited to advance research in many applications.
