Abstract

The problem of scattered broadband source localisation is addressed. It is shown that an accurate localisation requires both spatial and temporal processing of the array data owing to coherence loss across the array due to the scattering being frequency-selective. A computationally efficient localisation algorithm is then developed, based on applying the covariance matching method to the frequency domain snapshots. The main feature of the algorithm is that no model is required for the spatial coherence loss function
