Abstract

A 3D (angle-angle-range) imaging laser radar (LADAR) based on multiple-input multiple-output structure is proposed. In the LADAR, multiple coherent beams are randomly phased to form the structured light field and an APD array detector is utilized to receive the echoes from target. The sampled signals from each element of APD are correlated with the referenced light to reconstruct the local 3D images of target. The 3D panorama of target can be obtained by stitching the local images of all the elements. The system composition is described first, then the operation principle is presented and numerical simulations are provided to show the validity of the proposed scheme.
