Adaptive Presort Processing

Abstract

This report summarizes analysis and experiments of an optical signal processing architecture which excises narrow components from wideband signals using frequency plane excision. It is shown that area detection in the frequency plane is equivalent to point detection in the image plane. The design, construction, and testing of a detection system that obtains the Fourier transform of the wideband signal and adaptively searches for strong narrowband components are described. Computer simulations and experimental results of pulsed experiments are presented.
