Abstract
An approximate algorithm of calculating the amplitude of an echo signal from a standard flat-bottom reflector as a function of the coordinates of the reflector is considered. The acoustic signal is assumed to be emitted and received by either a normal (straight beam) piezoelectric probe with an arbitrary shape of the active surface or a multielement probe (antenna), the separate control of its elements being possible. Both tone and pulse excitations of the probe are considered.
