Abstract
Monofrequency continuous wave signals of long duration are used as inputs form sources of known characteristics and location. These signals are reflected off subterranean features and serve to paint the features for display and evaluation. A primary feature is the use of continuous wave, long duration signals as opposed to the standard short pulse technique.
