Though small in weight, the images it produced have a high spatial resolution of 1 m and a large observation width of 100 km. The first batch of images obtained within the first week after the launch confirmed the rich information in the data, including sea ice, wind, wave, rip currents, vortexes, ships, and oil film on the sea, as well as landmark buildings. Furthermore, geometric characteristics of sea ice, wind vector, ocean wave parameter, 3D features of buildings, and some air-sea interface phenomena in dark spots could also be detected after relevant processing. All these indicate that HISEA-1 could be a reliable, remarkable, and powerful instrument for observing oceans and lands.<\/jats:p>","DOI":"10.3390\/rs13112076","type":"journal-article","created":{"date-parts":[[2021,5,25]],"date-time":"2021-05-25T22:02:23Z","timestamp":1621980143000},"page":"2076","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["HISEA-1: The First C-Band SAR Miniaturized Satellite for Ocean and Coastal Observation"],"prefix":"10.3390","volume":"13","author":[{"given":"Sihan","family":"Xue","sequence":"first","affiliation":[{"name":"State Key Laboratory of Marine Environmental Science, Xiamen University, Xiamen 361005, China"},{"name":"College of Ocean and Earth Sciences, Xiamen University, Xiamen 361005, China"},{"name":"Fujian Engineering Research Center for Ocean Remote Sensing Big Data, Xiamen 361005, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4935-2838","authenticated-orcid":false,"given":"Xupu","family":"Geng","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Marine Environmental Science, Xiamen University, Xiamen 361005, China"},{"name":"College of Ocean and Earth Sciences, Xiamen University, Xiamen 361005, China"},{"name":"Fujian Engineering Research Center for Ocean Remote Sensing Big Data, Xiamen 361005, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5395-1374","authenticated-orcid":false,"given":"Lingsheng","family":"Meng","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Marine Environmental Science, Xiamen University, Xiamen 361005, China"},{"name":"Fujian Engineering Research Center for Ocean Remote Sensing Big Data, Xiamen 361005, China"},{"name":"College of Earth, Ocean and Environment, University of Delaware, Newark, DE 19716, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ting","family":"Xie","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Marine Environmental Science, Xiamen University, Xiamen 361005, China"},{"name":"College of Ocean and Earth Sciences, Xiamen University, Xiamen 361005, China"},{"name":"Fujian Engineering Research Center for Ocean Remote Sensing Big Data, Xiamen 361005, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Huang","sequence":"additional","affiliation":[{"name":"College of Earth, Ocean and Environment, University of Delaware, Newark, DE 19716, USA"},{"name":"Joint Institute for Coastal Research and Management (Joint-CRM), University of Delaware\/Xiamen University, Newark, DE 19716, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6578-6970","authenticated-orcid":false,"given":"Xiao-Hai","family":"Yan","sequence":"additional","affiliation":[{"name":"College of Earth, Ocean and Environment, University of Delaware, Newark, DE 19716, USA"},{"name":"Joint Institute for Coastal Research and Management (Joint-CRM), University of Delaware\/Xiamen University, Newark, DE 19716, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"He, Y., Zhang, B., and Perrie, W.
