Online wave direction and wave number estimation from surface vessel motions using distributed inertial measurement arrays and phase-time-path-differences
Dirdal, Johann Alexander; Skjetne, Roger; Roháč, Jan; Fossen, Thor I. (Peer reviewed; Journal article, 2022)A common approach for finding the direction of ocean waves is to use the phase-time-path-differences (PTPDs) between a static array of various types of sensors mounted on either the sea surface or seabed. However, some ... -
A phase-time-path-difference approach for online wave direction and wave number estimation from measured ship motions in zero and forward speed using a single inertial measurement unit
Dirdal, Johann Alexander; Skjetne, Roger; Roháč, Jan; Fossen, Thor I. (Journal article; Peer reviewed, 2023)This study investigates the potential capability of a relatively new and unexplored signal-based approach for shipboard wave estimation. The approach uses the phase-time-path-differences (PTPDs) from an array of shipboard ...
