Paper Abstract

Optical adaptive processors using photorefractive crystals as time integrating devices have demonstrated greater than 40-dB cancellation of narrowband interference signals. However, we desire to use adaptive optical processors to null broadband radar jamming. We tested the performance of our photorefractive based adaptive processor using wideband noise signals (greater than 100 kHz). The system's operation and experimental results of both narrowband and wideband cancellation are described.
