摘要：

A model-based identification approach to localize a source by characterizing the associated acoustic wave and estimating its range from a passive measurement array is discussed. After developing models representing the propagation phenomenology and measurement system, a solution to this problem is obtained. First the pertinent wave parameters are identified using spectral and order estimation techniques and then the source is localized using weighted least-squares coupled to a ranging algorithm. The feasibility of this approach is demonstrated by applying it to noisy data simulated from a detailed model based on experimental parameters. © 1990.
