LOCALIZATION OF PLANE REFLECTORS USING A WIDE-BEAMWIDTH ULTRASOUND TRANSDUCER ARRANGEMENT

Using a wide-beamwidth ultrasound transducer arrangement to measure th e geometric position of plane reflectors is studied, The localization of objects is based on the computation of the time of flight (TOF) of the acoustic echoes by the determination of the intersection point of the acoustic wave fronts; the geometrical position of the object is th en estimated, As no mechanical moving devices are involved in the rang ing process, and fewer TOF measurements are required than that of an a ctive phased linear array, the system features intrinsically high oper ational reliability and fast dynamic response.
