TDOA/AOA Data Fusion for Enhancing Positioning in an Ultra Wideband System

This paper considers a new location scheme for ultra wideband (UWB) positioning system. The newly adopted scheme combines the time difference of arrival (TDOA) and the angle of arrival (AOA) positioning techniques in order to enhance the accuracy of the positioning system compared to the classical technique (TDOA). The new technique is simulated in a sports tracking application in a football field. Results are compared with results from a similar system using classical TDOA technique in order to establish a proof-of-concept. Simulation shows that the new technique is actually giving better performance with an acceptably longer processing time. This technique has the promise of boosting positioning accuracy with a relatively low level of complexity.
