Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

The article introduces a groundbreaking dual-sparse parallel nested array (DS-PNA) designed for high-precision two-dimensional direction of arrival (DOA) estimation. Unlike existing arrays, the DS-PNA enhances array aperture and reduces mutual coupling by enlarging inter-antenna spacings. The systematic procedure for determining antenna positions maximizes the degrees of freedom in the difference coarray domain, resulting in robust and unique DOA estimates. The novel design offers superior performance in both pitch and azimuth angle estimation, as demonstrated through extensive simulations. The DS-PNA's ability to provide stable and accurate estimates even in the presence of mutual coupling makes it a standout solution in the field of DOA estimation.
