    I am trying to determine whether or not ENVI has a tool that can calculate the power spectral density of a fourier transformed image. I can't seem to find such an option......

    ENVI does not have this tool, but it looks like some users have written some IDL code to do it: http://www.astro.washingt...o/library28.html?PSD http://www.rxollc.com/idl/topo.html#PLOT_PSD
