Abstract

PURPOSE: To ensure the desired correct measurement, while eliminating the drawback that such a reflected pulse wave as uses a conventional pulse modulated wave is deformed to make incorrect the time interval measurement between the transmitted pulses and the received pulses, by using the transmitted waves which have their frequency modulated.
