    Abstract: The SAR Point Cloud Generation System processes synthetic aperture radar (SAR) data acquired from multiple spatially separated SAR apertures in such a manner as to be able to calculate accurate three-dimensional positions of all of the scatterers within the imaged scene. No spatial averaging is applied thus preserving the high resolution of the original SAR data, and no phase unwrapping processes are required. The effects of height ambiguities are significantly reduced in the SAR Point Cloud Generation System. The SAR Point Cloud Generation System also self-filters against mixed-height pixels that can lead to incorrect height estimates. The system estimates scatterer height by a maximization of an Interferometric Response Function.
