Abstract

Radio frequency signal processing systems that use photorefractive crystals to provide key functions are described. Some new experimental results obtained with a time-integrating correlator developed to support the acousto-optic null steering processor effort are presented that demonstrate the effectiveness of the photorefractive time-integrating approach. We also describe a new adaptive notch filtering system that provides effective and flexible excision of narrowband interference. The system architecture makes optimal use of the unique properties of the photorefractive effect to provide a simple yet highly effective solution for the adaptive signal processing problem.
