The focus of this book is on filtering for linear processes, and its
primary goal is to design linear stable unbiased filters that yield an
estimation error with the lowest root-mean-square (RMS) norm. Various
hierarchical classes of filtering problems are defined based on the
availability of statistical knowledge regarding noise, disturbances, and
other uncertainties.
The authors employ a structural approach for several aspects of filter
analysis and design, revealing an inherent freedom to incorporate other
classical secondary engineering constraints in filter design. This
approach requires an understanding of powerful tools that then may be
used in several engineering applications besides filtering.
Filtering Theory is aimed at a broad audience of practicing engineers,
graduate students, and researchers in filtering, signal processing, and
control. The book may serve as an advanced graduate text for a course or
seminar in filtering theory in applied mathematics or engineering
departments. Prerequisites for the reader are a first graduate course in
state-space methods as well as a first course in filtering.
