- W1999551462 abstract "AbstractA coherent optical processor is described which can be used to detect and locate objects in the sky thatmove against a background of fixed objects. A succession of sky images is recorded by multiple exposure onphotographic film with the imaging system stabilized on the stars. Stars appear as points in the compositeimage, and moving objects create streaks. Space invariant pattern recognition is performed on this compositeimage by generating its two -dimensional Fourier transform (spatial frequency spectrum) and scanning it witha rotating spatial filter matched to the streak spectrum. The filter angle at maximum energy transmissiondetermines the streak direction and a second Fourier transform provides coordinate information. The designof the optical system is described and some initial experimental results are shown.IntroductionAn effective midcourse ballistic missile defense (BMD) system requires the ability to launch an intercep-tor toward an incoming threat at the earliest possible time in order to find and destroy it. A hominginterceptor must be capable of searching a large sky sector and detecting the presence of a threat whilediscriminating among numerous other objects. Although simple in concept, the search task requires an enor-mous amount of computing power and data storage capacity. The trend in sensor design indicates that improvedsensor capabilities for BMD systems can be expected to increase the data rate by several orders of magnitudeover that of present sensors. The ability to handle these high data rates is important for advanced BMDsystems, especially when size, space, and weight are limited, as they are aboard a homing interceptor.This paper presents some initial results obtained in a program funded by the U. S. Army's BMD AdvancedTechnology Center (BMDATC). The program objective is to evaluate the capabilities of optical data process-ing to serve as an on -board preprocessor for the large volume data outputs from mosaic optical sensor arrays.Two processing phases are being considered:" @default.
