Two viewing angles for holographies in radar and light

In this work, a new topic, which is to synthesize (recover) the holograms between two or more recorded holograms with a large angle discrepancy, is presented. The technique aims at enlarging view angle, speeding up the recording process by reducing sensing points, and increasing resolution in holographic radar and light. Our method to tackle the problem is proposed. We analyze the problem in both single target and multiple targets cases. Given recorded magnitudes at receiving elements, nearby magnitudes of virtual receiving elements can be approximated. The accuracy of the approximation is also evaluated.
