Improved Wideband Source Localization
- 技術優勢
- - 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)
- 技術應用
- - Multiple wideband source localization
- 詳細技術說明
- 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.
