Spectral estimation techniques with special reference to sonar signal processing
A. Arcese, L. E. Bergeron · The Journal of the Acoustical Society of America · 1976
In this talk we present a comparative evaluation of several spectral estimation techniques. The estimation procedures investigated are the FFT and autoregressive modeling of the time domain waveform. For the autoregressive modeling the estimation procedures considered are the Durbin recursion, Burg recursion, Kalman filtering, and a gradient technique. We also present a new maximum entropy gradient spectral estimation procedure. The results of applying these spectral estimators to real submarine target data are presented.
