Abstract

Spectral estimation for a class of smooth, broad spectra generated by the turbulent boundary layer is discussed in terms of spectral fidelity and sensitivity to statistical error. When the number of sensors is limited, which is often the case in array problems, MLM-based estimators exhibit better performance than all-pole models. These performance differences underscore the fact that for certain classes of spectra high-resolution and high-fidelity are competing criteria.
