An analysis of the IIR an FIR Wiener filters with applications to underwater acoustics
(Monterey, California. Naval Postgraduate School, 1997-06)
A detailed analysis of the performance the Wiener optimal filter for estimating a signal in additive noise is carried out. A first order AR model is assumed for both the signal and noise. Both IIR and FIR forms of the ...
Detection and identification of cyclostationary signals
(Monterey, California. Naval Postgraduate School, 1996-03)
Propeller noise can be modeled as an amplitude modulated (AM) signal. Cyclic Spectral Analysis has been used successfully to detect the presence of analog and digitally modulated signals in communication systems. It can ...
Three-dimensional finite element model of a high power, low frequency ring-shell flextensional sonar transducer
(Monterey, California. Naval Postgraduate School, 1992-12)
A three-dimensional finite element model of a high power, low frequency ring-shell flextensional transducer (Sparton of Canada, Ltd. Model 34A0610 (Ref. 1) was developed for use with the ATILA code (Ref. 2). This transducer ...
