Some features of echo signals of longitudinal waves from flat-bottom reflectors in the far-field zone of a normal transceiver

Abstract
Features of reflection of longitudinal elastic waves from flat rectangular, elliptic, and segmental reflectors (flaws) placed in the far-field zone of a normal transceiver are investigated for continuous (quasi-monochromatic) and pulsed transmission-reception modes. It is shown that, as the dimensions of the reflector increase, the echo-signal amplitude oscillates and approaches a value determined by the limiting shape of this type of reflector. It has been established that, for the reflector models considered, the character of an echo signal is determined by the value of the generalized parameter depending on the distance to the reflectors, their characteristic dimensions, and the wave number of the acoustic wave.
