It is pointed out that, in the field of oil well drilling, EM-MWD (electromagnetic measurement while drilling) offers many advantages. The EM-MWD system can transmit measured data from the well bottom to the surface at high speed using electromagneti

In recent years, linear FM wave pulses and phase modulated wave pulses have been used to improve resolution and signal to noise ratios. In this paper, we report on transient sound fields generated by a sound source which is driven by linear FM wave p

A Method using linear FM ultrasonic wave to detect near-surface flaws and to measure distances from a surface to the flaw (flaw depth) in billets is presented. To test the ability of the detection and the measurement of this method, experiments were
