Tracking Accuracy Improvement Using Noisy Target Orientation Measurements

摘要

This paper discusses to what extent target-image information can improve theperformance of a radar-based-target-tracking system and how accurate this information must be to provide a substantial improvement in tracker performance. The degree of improvement of tracker performance obtained by supplementing radar-derived position and velocity information with optical-image-derived attitude information is investigated for several examples of maneuvering aircraft and ground vehicles. The effects of tracking condition factors such as measurement accuracy, maneuver intensity and prediction time are considered.
