The system focuses on multi-channel synchronization under a high sampling rate and multi-channel amplitude and phase calibration under large bandwidth to form an all-digital, low-power, multi-channel, high-speed, large bandwidth hardware platform suitable for broadband digital array signal processing. Through the implementation of the Multiple-Input Multiple-Output phased-array digital beamforming algorithm, the test conducted verifies that the system has superior signal processing performance of the broadband digital array.<\/jats:p>","DOI":"10.3390\/rs15164043","type":"journal-article","created":{"date-parts":[[2023,8,16]],"date-time":"2023-08-16T10:08:09Z","timestamp":1692180489000},"page":"4043","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Design of a Digital Array Signal Processing System with Full Array Element"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-3605-8736","authenticated-orcid":false,"given":"Guoyao","family":"Xiao","sequence":"first","affiliation":[{"name":"Department of Remote Sensing Science and Technology, Xidian University, Xi\u2019an 710071, China"},{"name":"Xi\u2019an Key Laboratory of Advanced Remote Sensing, Xi\u2019an 710071, China"},{"name":"Key Laboratory of Collaborative Intelligence Systems, Ministry of Education, Xidian University, Xi\u2019an 710071, China"}]},{"given":"Yinghui","family":"Quan","sequence":"additional","affiliation":[{"name":"Department of Remote Sensing Science and Technology, Xidian University, Xi\u2019an 710071, China"},{"name":"Xi\u2019an Key Laboratory of Advanced Remote Sensing, Xi\u2019an 710071, China"},{"name":"Key Laboratory of Collaborative Intelligence Systems, Ministry of Education, Xidian University, Xi\u2019an 710071, China"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-3816-3131","authenticated-orcid":false,"given":"Zongzheng","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Remote Sensing Science and Technology, Xidian University, Xi\u2019an 710071, China"},{"name":"Xi\u2019an Key Laboratory of Advanced Remote Sensing, Xi\u2019an 710071, China"},{"name":"Key Laboratory of Collaborative Intelligence Systems, Ministry of Education, Xidian University, Xi\u2019an 710071, China"}]},{"given":"Bo","family":"Wen","sequence":"additional","affiliation":[{"name":"Department of Remote Sensing Science and Technology, Xidian University, Xi\u2019an 710071, China"},{"name":"Xi\u2019an Key Laboratory of Advanced Remote Sensing, Xi\u2019an 710071, China"},{"name":"Key Laboratory of Collaborative Intelligence Systems, Ministry of Education, Xidian University, Xi\u2019an 710071, China"}]},{"given":"Guisheng","family":"Liao","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Radar Signal Processing, Xidian University, Xi\u2019an 710071, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1197","DOI":"10.1109\/TMTT.2018.2889038","article-title":"An integrated radar tile for digital beamforming X-\/Ka-band synthetic aperture radar instruments","volume":"67","author":"Arnieri","year":"2019","journal-title":"IEEE Trans.
