Abstract: Sparse arrays designed based on fourth-order difference co-array (DCA) can achieve significantly higher uniform degrees-of-freedom (uDOFs). However, most existing fourth-order sparse arrays ...
A new study analyzing historical photographs taken by the Palomar Observatory between 1949 and 1957 has detected several mysterious bright spots in the sky. These transient objects, captured on film ...
Have you ever wondered why the sight of a child born male at birth wearing a dress makes adults so uncomfortable? Or why the new family in town that does not attend religious services in a small ...

Astronomers have discovered a strange new object in our Milky Way. An international team reported Wednesday that this celestial object — perhaps a star, pair of stars or something else entirely — is ...
Abstract: Recently, numerous design schemes for high-order sparse linear arrays (SLAs) have been introduced for underdetermined direction-of-arrival (DOA) estimation based on high-order cumulants, ...
