Abstract

The purpose of the paper is to answer the question if and what kind of information can be obtained from the grey scale shadow of targets detected by means of short ultrasonic pulses. The theory of wave reflection from spherical obstacles was applied for determination of the shadow caused by plane wave pulses incident on rigid, steel, gaseous spheres as well as on spheres made of kidney stones immersed in water.
