Optical Excisor Modeling

Abstract

This work simulates an acousto-optic signal processing technique that can be used to filter radio-frequency (RF) electronic signals. Of particular interest is the removal or excision of narrowband interference from broadband signals. The program developed simulates the performance of a binary phase shift keying (BPSK) signal with a narrowband interference. The width and depth of notches that model an excisor-detector array are variable. In addition there is a capability to move the notches in order to place a notch over the interference for maximum filtering capability. A summary of several possible excisor techniques is presented. Optical excisor, Bragg cell, Acousto-optic, Spectrum analyzer, Excisor detector.
