Synthetic Interferometric Imaging Technique for Moving Objects.

摘要

It is shown, theoretically and experimentally, that an object traveling through an interference field formed by two coherent point sources can be imaged via synthetic aperture techniques. The time varying signal scattered by the object is electronically detected and then recorded spatially such that the recording is a one-dimensional hologram of the object. The synthetic angular aperture of the hologram is proportional to the angle subtended by the pathlength of the object and is dependent on the geometrical arrangement of the point sources with respect to the position and velocity of the object.
