Abstract:

A digital six state estimator was developed to aid the Bendix ASCOT Adaptive Scan Optical Tracker in the presence of background clutter. Laboratory tests were conducted at the US Air Force Academy Guidance and Control Laboratory to determine the basic accuracy of the ASCOT in a laboratory environment. During the tests the ASCOT tracker was successfully aided through various kinds of background clutter by two different methods. The first method was to aid the ASCOT in the presence of background clutter using an independent sensor. In the laboratory, this independent sensor signal consisted of the true target position corrupted by radar-type noise. The second method was to drive the ASCOT with the digital estimator during the presence of background clutter. The ASCOT tracker demonstrated remarkably low noise characteristics. The ASCOT noise levels in the laboratory on the azimuth and elevation signals were on the order of .25 milliradians or less. The tests substantiated the concept of improving the ASCOT tracker for employment as a sensor in a director type gunsight. Author
