The Effect of Scene Rotation on Target Acquisition and Tracking.
Abstract
Three studies were performed to determine the effects of scene rotation on target acquisition and tracking performance. Video tapes of simulated straight-in approaches to surface vehicular targets were made at constant offset, altitude and speed using a terrain table (600:1) and a gimbal-mounted TV camera. Detection and (separate) recognition tests were then made under load (button-pushing) and no-load conditions. No difference in detection slant range and erroneous detections were found between the rotated (roll-pitch) and non-rotated (yaw-pitch gimbal order) conditions or between the load-no load conditions. Statistically significant differences were found between the recognition ranges and error scores for gimbal order but again not between load-no load conditions. When 30 subjects were asked to track rotated and nonrotated targets resulting from gimbal order; significant differences were found in tracking error scores. It was concluded that every attempt should be made to stabilize or deroll the sensor LOS if maximum recognition and tracking performance is to be realized using airborne electrooptical systems in ground target acquisition and tracking.
