THE MEASUREMENT OF INCIDENT AND REFLECTED SPECTRA USING A LEAST SQUARES METHOD

E.P.D. Mansard, E.R. Funke

Abstract


A least squares method to separate the incident and reflected spectra from the measured co-existing spectra is presented. This method requires a simultaneous measurement of the waves at three positions in the flume which are in reasonable proximity to each other and are on a line parallel to the direction of wave propagation. Experimental investigations have shown that there is good agreement between the incident spectra calculated by the least squares method and the incident spectra measured concurrently in a side channel.
