Abstract

Synthetic aperture (SA) imaging methods and systems are assisted by three-dimensional (3D) beam scanning imaging, for example scanning lidar. The methods can include concurrently acquiring an SA image and a 3D scanning image of a target region, determining an elevation map of the target region from the 3D scanning image, and processing the SA image based on the elevation map to provide or enhance 3D imaging capabilities in the SA image. In some implementations, the SA image is a two-dimensional (2D) SA image and the elevation map is used to orthorectify the 2D SA image. In other implementations, the SA image is a phase-wrapped 3D SA image resulting from the combination of two or more 2D SA images and the elevation map is used to perform phase unwrapping on the phase-wrapped 3D SA image.
