【Abstract】 To carry out spectral analysis for observation data with small size according to a certain spectral resolution and variance,the maximum entropy method(MEM) was introduced based on the fast Fourier transform(FFT) algorithm.The computational principle and example were provided and a comparison of calculation results with FFT and bootstrap FFT was provided.Computational results show that MEM is effective to treat with the record of the stationary and ergodic stochastic process such as sea wave within time domain.更多还原
