The completed Allen Telescope Array (ATA) is intended to consist of approximately 350 6.1 meter offset Gregorian dishes at the Hat Creek Radio Observatory site in northern California. Given the number ...

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 do not ...

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, which utilize ...
