Abstract

The authors have proposed an ultrasound FMCW range-measuring system for diagnosis. In the proposed system, a transmitter and receiver operate at very low voltage. It is desirable to compose a simple transmitter and receiver and to protect the human body against damage caused by ultrasound power. The system results analyzed using saw-tooth and isosceles modulation waveform agreed with experiment results derived using delay lines.
