Design and Calibration of an Airborne Multichannel Swept-Tuned Spectrum Analyzer

The NASA STI Program Office...in ProfileSince its founding, NASA has been dedicatedto the advancement of aeronautics and spacescience. The NASA Scientific and TechnicalInformation (STI) Program Office plays a keypart in helping NASA maintain thisimportant role.The NASA STI Program Office is operated byLangley Research Center, the lead center forNASA's scientific and technical information.The NASA STI Program Office provides accessto the NASA STI Database, the largest collectionof aeronautical and space science STI in theworld. The Program Office is also NASA'sinstitutional mechanism for disseminating theresults of its research and development activities.These results are published by NASA in theNASA STI Report Series, which includes thefollowing report types:TECHNICAL PUBLICATION. Reports ofcompleted research or a major significantphase of research that present the results ofNASA programs and include extensive dataor theoretical analysis. Includes compilationsof significant scientific and technical dataand information deemed to be of continuingreference value. NASA's counterpart ofpeer-reviewed formal professional papers buthas less stringent limitations on manuscriptlength and extent of graphic presentations.TECHNICAL MEMORANDUM. Scientificand technical findings that are preliminary orof specialized interest, e.g., quick releasereports, working papers, and bibliographiesthat contain minimal annotation. Does notcontain extensive analysis.CONTRACTOR REPORT. Scientific andtechnical findings by NASA-sponsoredcontractors and grantees.CONFERENCE PUBLICATION.Collected papers from scientific andtechnical conferences, symposia, seminars,or other meetings sponsored or cosponsoredby NASA.SPECIAL PUBLICATION. Scientific,technical, or historical information fromNASA programs, projects, and mission,often concerned with subjects havingsubstantial public interest.TECHNICAL TRANSLATION. English-language translations of foreign scientificand technical material pertinent toNASA's mission.Specialized services that complement the STIProgram Office's diverse offerings includecreating custom thesauri, building customizeddatabases, organizing and publishing researchresults...even providing videos.For more information about the NASA STIProgram Office, see the following:• Access the NASA STI Program Home Pageat http://www.sti.nasa.gov• E-mail your question via the Internet tohelp@sti.nasa.gov• Fax your question to the NASA Access HelpDesk at (301) 621-0134• Telephone the NASA Access Help Desk at(301) 621-0390Write to:NASA Access Help DeskNASA Center for AeroSpace Information7121 Standard DriveHanover, MD 21076-1320
