资源简介：
"Time series data must be prepared for the discrete Fourier transform by removing wild points (fliers), as well as slowly varying trends or components, since both upset spectral validity and resolution. An editing/detrending procedure to do this (complete with a FORTRAN subroutine) is presented. The method is analyzed and tested on CODAR (Coastal Ocean Dynamics Applications Radar) data with good results."
