Abstract: Sparse linear arrays (SLAs) offer advantages in reducing hardware costs and complexity but pose challenges for traditional signal processing algorithms requiring a complete covariance matrix ...

Abstract: When the array aperture is constrained to no more than three wavelengths, accurate estimation of the direction of arrival (DOA) and reliable acquisition of the corresponding target signals ...

Despite significant mathematical refinements, econometrics has shown the weaknesses of its logical underpinnings, primarily during economic turning points—financial crises, pandemics, and geopolitical ...
