Jy. Sheng et Ae. Hay, SPHERICAL WAVE BACKSCATTER FROM STRAIGHT CYLINDERS - THIN-WIRE STANDARD TARGETS, The Journal of the Acoustical Society of America, 94(5), 1993, pp. 2756-2765
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.
