@article{Chapman_Cotaras_1991, title={Acoustic backscattering from cylinders: near-field corrections}, volume={19}, url={https://jcaa.caa-aca.ca/index.php/jcaa/article/view/674}, abstractNote={In the course of making TS (target strength) measurements of hollow aluminum cylinders of length 91 cm and 28 cm in the frequency range 30-36 kHz, the authors realized that their measurements were being corrupted at beam aspect because the source and receiver were in the near-field of the target. Fortunately, they were able to increase the range and reduce this effect, but they also derived a correction to the near-field TS measurements that could be applied if sufficient range were unavailable. The derivation and application of this beam-aspect TS correction is the subject of the present work}, number={4}, journal={Canadian Acoustics}, author={Chapman, D.M.F. and Cotaras, F.D.}, year={1991}, month={Sep.}, pages={71–72} }
