- W2072841326 abstract "AbstractApplications of fiber and integrated optics to wideband radar signal processing arediscussed. The systems requirements dictated by radar parameters (e.g., time -bandwidthproduct, dynamic range, etc.) are indicated and it is shown that optical techniques canprovide a means for meeting these requirements. Examples of applications which arediscussed include: (1) fiber -optic delay lines for pulse -to -pulse integration ofwideband, high -resolution radar returns; (2) implementation of a noncoherent,high -resolution moving target indicator (MTI); (3) fiber -optic tapped delay lines for useas matched filters for detection, identification, and pattern recognition; and (4) a high -speed electro -optic analog -to- digital (A /D) converter. The devices required for realization of the above are described. These devicesinclude laser diodes, avalanche photodiodes, and optical waveguides and switches. The properties of optical fibers relative to their application to the signal processingfunctions above are also discussed.IntroductionIn recent years, glass fibers for use as a transmission medium for broadband signalshave been developed and improved.(1,2) Similarly, research in integrated optics hasled to the development of broadband optical components which provide processing andinput /output capabilities for use with optical fibers. Much of the prior research anddevelopment efforts have been directed towards communications applications. Recently,however, it has been realized that there are also important potential uses for thesetechnologies in radar systems, especially those requiring generation and processing ofextremely broadband ( >500 MHz, e.g.) signals.(3) Basic signal processing functionswhich can be performed using optical fibers include signal delay, matched filtering, anddata storage; while integrated optics can be used for analog -to- digital (A /D) conversion,switching, and for signal modulation and demodulation at the termination of fiber delay" @default.
