The proposed multichannel acousto-optic bragg cell spectrum analyzer offers nasa gsfc a solution to the processing of wide bandwidth RF spectral information. Acousto-optic spectrum analyzers are used in military EW and ELINT applications. The extension of this technology to a 2-d n channel bragg cell processor gives an n fold increase in bandwidth capability, which is necessary for NASA's application. The objectives of this research are to demonstrate the multichannel acousto-optic bragg cell spectrum analyzer concept, and also demonstrate the long integration time required for NASA's applications. Once this system is successfully demonstrated, it is possible to address. Other NASA ground and space borne applications that can utilize this acousto-optic spectrum analyzer system. A six month program is proposed to design, implement, and demonstrate the multichannel acousto-optic spectrum analyzer.
