  • This paper presents a new method for ultrasonic ranging. It consists on continuously transmitting a signal composed by multiple sine wave segments, each containing an integer number of periods. The frequency of each segment is different from the adjacent segments, but close to the transducer resonant frequency, to minimise the filtering effects of the system. The transmitted and received signals are cross-correlated to determine the time-of-flight (TOF). Parabolic interpolation on the cross… CONTINUE READING
