Array Signal Processing for Non-Stationary Signals

The work of this thesis is concerned with array signal processing; the term array implying a manifold of sensors is employed to produce observations of some measurable quantity. The type of signals measured by the array will depend on the application for which it is designed. For example sensor arrays have been used in such fields as communications, sonar, manufacturing processes and image reconstruction. In any of these applications, the goal of signal processing at the output of the array is to extract important information about the originating signals, of which only a mixture is observed. Information to be estimated may be the number of significant sources impinging on the array, the spatial location of the sources or the originating source signals themselves.

The focus of this research is on array signal processing for non-stationary signals. The signals are assumed to be deterministic with a time- varying spectral content, such as frequency-modulated (FM) signals. Interference signals in spread spectrum communications systems may belong to a class of FM signals. FM signals are also encountered in the fields of radar and sonar. Techniques for detection, estimation and classification of these signals using information from sensor arrays is the goal of this work.
