Short Range Positioning Using Ultrasound Techniques
In this paper, a positioning technique based on measuring the Time Difference of Arrival (TDoA) of ultrasonic chirp pulses is proposed. The implementation issues of the proposed method are discussed and the development of two versions of low-complexity prototype is presented. Experimental results from a measurement campaign using the realized prototype are presented, demonstrating sub-centimeter position measurement accuracy in the short range, thus validating the proposed technique.
