PERFORMANCE STUDIES ON THE NOTS-UCLA TRACKING SIMULATOR WITH TWO OPTICAL SYSTEMS AND A SWITCHING OPTION

摘要

An experiment was performed on the NOTS-UCLA Tracking Simulator to test the feasibility of using a mechanical switching device to switch be¬tween two optical systems in an effort to combine the best effects of both. The beneficial effects of small probability of target loss and of easy reacquisition available with a large field of view and low power magnification (13 , IX) would thus be coupled with the lower tracking error generally obtained with optical systems employing limited field of view and moderate magnification (5 , 5X). As expected, the 5 5X optical display yielded significantly lower tracking error than the 13 , IX display. The inclusion of a switching option did not further improve performance. Theo¬retical considerations indicate that a switching device may be more bene¬ficial for more difficult tasks and when initial acquisition is included as a part of the task.
