Professional Society Honors Navy Engineer
Bethesda, Maryland
April 2, 2001

The National Society of Professional Engineers selected Dr. Dale Groutage as one of the top ten federal engineers of the year as part of its 22nd Annual Federal Engineer of the Year Award Program. NSPE is recognizing Groutage for achievements in the fields of time-frequency analysis and applied mathematics. His contribution to time-frequency analysis is development of the fast algorithm for constructing two-dimensional positive time-frequency distributions. The Navy used this analyzing acoustic scattering data or "target strength" for missile launching attack submarines, supporting design decisions for the new attack submarine, USS VIRGINIA (SSN 774). Accomplishments in applied mathematics include development of a new matrix decomposition, transposed singular value decomposition. Both the Navy and NASA use this: the Navy processing submarine sonar acoustic transients and NASA processing flight data. ONR sponsors his work through the NSWC Carderock Division's In-house Laboratory Independent Research Program.

Previous honors include: Best In-House Laboratory Independent Research (ILIR) Project, NSWC, 1999; Award of the Office of Naval Technology Certificate of Commendation for Development of Near-Field Measurement Technology, 1992; BEST FY1991 Independent Exploratory Development Project, Determination of the Acoustic Scattering Cross-Section (Target Strength from Coherent Near-Field Measurements, NSWC, 1991; David Taylor Research Center Certificate of Special Act or Service Award for the first Acoustic Holography measurement of a full-scale U.S. submarine, the USS TAUTOG, 1989. He holds five U.S. Patents with one pending and has co-authored three books.

His career began with the Naval Weapons Station in Corona, CA in 1968. He joined the Puget Sound Detachment of the Carderock Division (then known as the David Taylor Research Center) in Bremerton, WA in 1988.

Groutage holds a bachelor's, master's and a doctorate in electrical engineering from the University of Wyoming.
