Abstract
The TDoA (Time Difference of Arrivals) based location tracking systems using the RF and ultrasonic signals often give unacceptable errors due to the line-of-sight limitation of the ultrasonic signal. Overcoming this limitation, this paper proposes a novel TDoA based location tracking technique that explicitly exploits the ultrasonic reflection scenarios in the target location estimation. The proposed system can achieve a high location accuracy with errors smaller than 23 cm even when the lines-of-sight of ultrasonic signals are blocked pretty often and hence they are received through reflections.
