continuedTECHNICAL PAPER ABSTRACTS:The Radio SpectrumA Critical Resource for T&EDarrell E.ErnstThe MITRE Corporation,McLean VirginiaThe radio spectrum is a critical resource for a large percentage of test and evaluation(T&E)endeavors and for thedevelopment programs for which the T&E is conducted.This has been true for military weapon systems at least since1912 when radios began to be used in airplanes.For many years,the development and test communities used theradio spectrum with little concern about availability or access.The invention ofsolid-state electronics and the emer-gence ofthe“Moores Law”phenomenon changed all that.The combination ofexplosive growth in commercial spec-trum consumption and solid-state electronics capabilities has moved spectrum access for T&E to the top ofthe list ofthreats facing the ability to test weapon systems adequately.The challenges ofmaintaining adequate radio spectrumare not limited to the test community;the entire U.S.Department ofDefense is struggling with the changing worldofelectromagnetic spectrum usage.This article addresses the challenges ofensuring adequate spectrum for T&E andproposes treating spectrum as cost elements in the acquisition
