Wideband DOA Estimation using Two Sensors

摘要：

This paper proposes an efficient irection-of-arrival (DOA) estimation algorithm for wideband signals from data collected using two sensors. Like the traditional wideband methods, this algorithm first decomposes wideband sources into narrowband bins. At each frequency bin, the crosscorrelation between sensors is estimated to construct a Toeplitz matrix, which contains all angle information. Thus the physical size between two sensors is independent of the frequency bins and relies more on the inter-frequency bin difference. The proposed method is flexible in the design of the sensor array without inducing ambiguities. Simulation results confirm the ability of the proposed method that provides reliable estimates in multiple wideband signal environments.
