Determination of Directional Spectra of Sea Surface Wave Field by Scanning Observation,

Abstract

The paper considers the possibility of determining the directional energy spectrum of ocean surface gravity waves from a set of one-dimensional spectra. The one-dimensional spectra are in Doppler shifted frequency domain and they are obtained from the signal given by towing a measuring device in different directions across a wave field. An attempt to solve the integral equation involved approximating it by a set of simultaneous linear algebraic equations led to a singular matrix. (Author)
