Smart Optical Receiver for Beamforming and Enhancement of Field of View in LADAR Systems

Abstract

We propose using the smart antenna principle as the basis of a new design for smart optical receivers in LADAR systems. This paper demonstrates the feasibility of designing a LADAR system with a receiver consisting of an array of photodetectors, which leads to field-of-view enhancement and beamforming by fusing streams of video information received from the detectors. As a proof of concept, we demonstrate this design by fusing several video information streams from different fields of view using our Mathworks Simulink model. The fusion algorithm uses the fuzzy logic maximum operation on the data output from the cameras.
