文摘In this paper, the method of time series analysis——the maximum entropy spectrum estimation is used in setting up the track crosswise roughness power spectrum density functions (call simple “the track spectra”), the track spectra are obtained by process the data measured from the ground. The results obtained in the way are prove to be superior to those obtained with the "FFT" methods.
