Improved Wideband Source Localization

Technology Benefits: - Simultaneous estimation of closely spaced and disparate sources- Low computational cost in time and spatial domain processing (existing methods must process data after conversion to the frequency domain)- True time delay beamformer bank dimension can be less than the number of array elements- Non-iterative: single algorithm pass for entire field of view and no coarse preliminary estimation (existing methods may need multiple iterations) - High resolution (overcomes Rayleigh limit and Periodogram resolution)

Technology Application: - Multiple wideband source localization

Detailed Technology Description: None

*Abstract: The inventors created a new algorithm that can estimate direction of arrival (DOA) of multiple wideband sources. The algorithm uses multiple signal classification (MUSIC) subspace processing of data from a bank of true time delay beamformers. Simulation Results are available.
