| Abstract: | The use of some mathematical transforms in marine technology is specified in this paper based on the author's experience.The spectrum analysis,wave separation and cross-correlation analysis via Fourier transform are presented as well as its counterpart of Hartley transform.The application of continuous Morlet transform to time-frequency analysis of wave signals is stated,and the discrete orthogonal wavelet transform is explained for the use of de-noising and feature extraction from suspended sediment images.The formulae and data comparison are provided to show the scientific glamour of the mathematical transformation applied to marine technology. |
