Abstract
In the hydraulic laboratory environment a seperation of an irregular wave field into incident waves propagating towards a structure, and reflected waves propagating away from the structure is often wanted. This is due to the fact that the response of the structure to the incident waves is target of the model test.
Goda and Suzuki (1976) presented a frequency method for estimation of irregular incident and reflected waves in random waves. Mansard and Funke (1980) improved this method uaing a least squares technique.
In the following, a time-domain method for seperating the incident waves and the reflected waves (SIRW-method), is presented. the method is based on the use of digital filters and can seperate the waves fields in real time.
