The report presents the findings of an experiment designed to appraise the accuracy with which an operator can manually track a moving target by means of an electronic marker controlled by a joystick. Conclusions a The average bearing error made in operating the ETDE under a number of conditions of course, speed, range, SN ratio, and sweep rate is 1.22 degrees. b The average range error under the same conditions is 0.34 miles. In addition, the operators offered the opinion that it was easier to track fast targets than slow ones. They felt that more damping was needed in the manual-control mechanism for tracking low speed targets.
