Presort Processor.
Abstract
Optical notch filtering is a technique utilizing acousto-optics and Fourier Transform Optics to excise bands of frequencies from a radio frequency spectrum. The purpose of the presort processor is to excise strong narrow band signals from a wideband radar return. The intent of this project was to upgrade a processor built for Rome Laboratory by Harris Corporation by upgrading certain components which have been improved in the years since the beginning of the Harris project. This upgrade has not been completed because of delays in the fabrication of new spatial light modulators, the component which actually performs the excision. Because of this delay and other factors outlined in the remainder of this report we have decided to design an entirely new system under a new project. Many of the program goals in this project have not been met, but have been transferred to JON 4600P112.... Optical notch filtering, Optical RF spectrum analysis, Presort processor.
