If appropriately placed, the co-located transmit and receive arrays can make a large virtual aperture. This paper proposes a new method for designing arrays by adopting a structure with minimum redundancy. The proposed structure can significantly increase the virtual array aperture while keeping the transmit and receive antennas at the same size. We describe the application of the proposed method to subarray-type antennas using multi-channel transceivers, which is essential for arranging RF hardware in a small antenna operating at high frequency. Further, we present an analysis of the final beam pattern and discuss its benefits and limitations.<\/jats:p>","DOI":"10.3390\/rs15010078","type":"journal-article","created":{"date-parts":[[2022,12,27]],"date-time":"2022-12-27T07:30:06Z","timestamp":1672126206000},"page":"78","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Non-Uniform MIMO Array Design for Radar Systems Using Multi-Channel Transceivers"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5118-5509","authenticated-orcid":false,"given":"Eunhee","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Defence System Engineering, Sejong University, 209 Neungdong-ro, Gwangjn-gu, Seoul 05006, Republic of Korea"}]},{"given":"Ilkyu","family":"Kim","sequence":"additional","affiliation":[{"name":"Electrical and Electronics Engineering Department, Sejong Cyber University, 121, Gunja-ro, Gwangjn-gu, Seoul 05000, Republic of Korea"}]},{"given":"Wansik","family":"Kim","sequence":"additional","affiliation":[{"name":"LIGNex1 Co., 207 Mabuk-ro, Giheung-gu, Yongin-si 16911, Republic of Korea"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"22","DOI":"10.1109\/MSP.2016.2628914","article-title":"Automotive radars: A review of signal processing techniques","volume":"34","author":"Patole","year":"2017","journal-title":"IEEE Signal Process.
