Web1 de set. de 2005 · This thesis focuses on methodologies for estimation of directional wave spectra. The objective is to study and develop methods for estimating wave spectra on the basis of measured ship responses. Traditionally, such methods, which are derived by use of linear spectral analysis, are based on either a parametric or a non-parametric procedure. WebTaking heave, if the response amplitude operator is Yz ( ωE) for encounter frequency ωE, then the energy spectrum for the heave motions is: where Sw ( ωE) is the wave energy spectrum. This is illustrated in Figure 10.5 where AA= (AB) 2 (AC). Sign in to download full-size image. Figure 10.5. WebWilliam Thomson (the famous physicist Lord Kelvin) found already in 1887 the remarkable fact that the angle at which the wake fans out is always the same, regardless whether the wake is caused by a duck, a boat, or a ship, as long as the water is deep as compared with the lengths of the generated waves [1].

"WebThe wake generated by a moving ship may extend for many tens of kilometers in the open ocean, and can be remotely sensed. Through indirect methods, the detection of a ship and its related characteristics, is generally obtained by measuring the ship generated waves or their spectra. From the viewpoint of remote sensing, interesting problems exist related … " - On ship wave patterns and their spectra
