Portable imager

Abstract:

Embodiments provide for a portable imager by capturing several radar readings related to an object in an environment over several times from several of Points of View (POV), wherein each radar reading indicates a distance to and reflectivity of the object relative to the imager; capturing several camera images of the environment over the several of times from the several POVs; determining positional shifts of the imager over the several times based on photogrammetrical differences between subsequent camera images of the several camera images; determining, based on accelerometer data, a trajectory that the imager moves in the environment over the several times; determining positions of the imager in the environment over the several times based on the positional shifts and the trajectory; combining the several radar readings based on the positions to produce a synthetic aperture radar image of the object; and outputting the synthetic aperture radar image.
