A Novel Distance Measurement Approach Using Shape Matching in Narrow-Band Ultrasonic System

Nowadays, a large number of novel technologies and systems are invented in order to solve the problems of Indoor Positioning Systems (IPS). One of the most well- known and common positioning technology is ultrasound. The zero rooms’ leakage, low cost, scalability, reliability, and less complexity in hardware and computing are the main advantages of ultrasonic systems. However, existing ultrasonic systems are hampered by many problems such as uncertainty and reduced robustness. This paper contributes an approach with the intention of improving distance measurement for indoor robot positioning by using an ultrasonic sensor. In the proposed method, start point of received signal will be determined more precisely.
