A variety of arrays are designed for different purposes, and they perform poorly in scalability. In this paper, we consider a subclass of structured sparse arrays, namely nested arrays, and examine the important role of \u201ccoarray\u201d in interferometric synthesis imaging, which is utilized to design nested array configurations for a complete uniform Fourier plane coverage in both supersynthesis and instantaneous modes. Both nested arrays and the theory of the coarray have rich research achievements, and we apply them to astronomy to design arrays with good scalability and imaging performance. Simulated celestial source image retrieval performance validates the effectiveness of nested interferometric arrays.<\/jats:p>","DOI":"10.3390\/rs15071943","type":"journal-article","created":{"date-parts":[[2023,4,6]],"date-time":"2023-04-06T01:10:27Z","timestamp":1680743427000},"page":"1943","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Design of Extensible Structured Interferometric Array Utilizing the \u201cCoarray\u201d Concept"],"prefix":"10.3390","volume":"15","author":[{"given":"Qiang","family":"Wang","sequence":"first","affiliation":[{"name":"School of Electronic and Optical Engineering, Nanjing University of Science and Technology, Nanjing 210094, China"}]},{"given":"Cong","family":"Xue","sequence":"additional","affiliation":[{"name":"School of Electronic and Optical Engineering, Nanjing University of Science and Technology, Nanjing 210094, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2626-199X","authenticated-orcid":false,"given":"Shurui","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Electronic and Optical Engineering, Nanjing University of Science and Technology, Nanjing 210094, China"}]},{"given":"Renli","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Electronic and Optical Engineering, Nanjing University of Science and Technology, Nanjing 210094, China"}]},{"given":"Weixing","family":"Sheng","sequence":"additional","affiliation":[{"name":"School of Electronic and Optical Engineering, Nanjing University of Science and Technology, Nanjing 210094, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3080","DOI":"10.1109\/TAES.2019.2959897","article-title":"Simultaneous measurement of radial and transversal velocities using interferometric radar","volume":"56","author":"Wang","year":"2019","journal-title":"IEEE Trans.
