ABSTRACT:
A nonlinear technique for high-resolution data processing produces high-rlution power spectra from the output of a conventional processor. First, a "guess" of the spectral estimate is formed. Then the spectral estimate is convolved with the system response function to produce estimated output levels. The differences between the estimated output levels and the measured output levels are used to modify the spectral estimate to produce a new "guess". This process is repeated until certain criteria are satisfied.
