Abstract
Analytical results are obtained for the amplitude of a spherical wave backscattered from a solid cylinder immersed in water. The effects of transducer directivity and transmitted pulse duration are included. Ba ckscatter measurements for comparison with theory are made using strai ght stainless steel wires ranging from 0.13 to 0.26 mm diameter, and a coustic transceivers operating at 1, 2.25, and 5 MHz. The results are used to evaluate the use of thin wires as standard targets.
