“Signal enhancement” increases radar power effect

New FM-CW radar system developed by Columbia University, New York, N.Y., scientists and engineers at the University´s Electronics Research Laboratories for the U. S. Air Force raises the strength of a radar signal reflected from an aircraft or a missile “to an unprecedentedly high level” without any actual increase in the power used. This was described as being of particular significance for radar installations in regions like the Arctic, where it is extremely difficult to supply fuel and other facilities for producing large amounts of power.
