Abstract
A technique is developed to separate the incident and reflected waves propa gating on a known current in a laboratory wave-current flume by analyzing w ave records measured at two or more locations using a least squares method. It can be applied to bath regular and irregular waves. To examine its perf ormance, numerical tests are made for waves propagating on quiescent or flo wing water. In some cases, to represent the signal noise and measurement er ror, white noise is superimposed on the numerically generated wave signal. For all the cases, good agreement is observed between target and estimation . (C) 2001 Elsevier Science B.V. All rights reserved.
