What is the source of the image? The building in the background looks an awful lot like the National War College at Fort Lesley McNair in Washington, D.C.
Best,

The photo appears to have been taken at Bolling Field in Washington, D.C. The building in the background is indeed the United States Army War College at Washington Barracks (now Fort Lesley J. McNair). The Anacostia River (Eastern Branch of the Potomac River) lies between the two. Bolling Field was used by the U.S. Army Air Corps as well as U.S. Navy Aviation. Perhaps the original name of the base--the Anacostia Experimental Flying Field--when it opened in the late teens may help explain why acoustical tracking device testing was taking place.
