The Design of Wave Data Frequency-Domain Analysis Program

In this paper, a specific method is presented for designing program of wave data frequency-domain analysis, which includes basic principle and program implementation of Fast Fourier Transform, programming of power spectrum estimation and calculation and display of each order moment of wave spectrum. In the process of introducing FFT, we present specific program flow chart. While in the power spectrum estimation, this article mainly refers to the power spectrum calculation and power curve smoothing. According to the practical test, the program is stable, expeditious and accurate highly.
