Optical Digital Algebraic Processing for Multi-Sensor-Array Data.

Abstract

This research program centered on the investigation of low-accuracy analog opto-electronic methods for processing multi-sensor-array data (e.g., phased array radar, sonar). Two methods were considered for signal orthogonalization in low-accuracy preprocessors, one based on a resonant piezo-electro-optic modulator devices. Neither method appears to offer significant benefits over all-electronic preprocessor methods because of the lack of large-scale parallelism. An analog, continuous-time opto-electronic processor for adaptive phased array signal processing was also considered that does exhibit considerable parallelism and shows promise for use as a low-accuracy co-processor in a hybrid analog/digital configuration.
