A modified coarse-focused method with cubic chirp Fourier transform (CFT) is explored first that permits the coarsely focused imageries to be recovered, thus alleviated the impacts of GMT Doppler ambiguity and range cell migration (RCM). After that, in combination with joint-pixel model, a robust clutter suppression method which enhances the GMT integration, and improving the accuracy of radial speed (RS) recovery by modifying the matching between the beamformer center and GMT, is proposed. Due to that the first-order phase compensation and RS retrieval are predigested, the proposed algorithm has lower the algorithmic complexity. Finally, the feasibility of our proposed method are verified via experimental results based on simulated and real measured data.<\/jats:p>","DOI":"10.3390\/rs13112051","type":"journal-article","created":{"date-parts":[[2021,5,24]],"date-time":"2021-05-24T04:01:20Z","timestamp":1621828880000},"page":"2051","source":"Crossref","is-referenced-by-count":6,"title":["Robust Clutter Suppression and Ground Moving Target Imaging Method for a Multichannel SAR with High-Squint Angle Mounted on Hypersonic Vehicle"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7917-5908","authenticated-orcid":false,"given":"Jiusheng","family":"Han","sequence":"first","affiliation":[{"name":"National Laboratory of Radar Signal Processing, Xidian University, Xi\u2019an 710071, China"}]},{"given":"Yunhe","family":"Cao","sequence":"additional","affiliation":[{"name":"National Laboratory of Radar Signal Processing, Xidian University, Xi\u2019an 710071, China"}]},{"given":"Tat-Soon","family":"Yeo","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Ehgineering, National University of Singapore, Singapore 119077, Singapore"}]},{"given":"Fengfei","family":"Wang","sequence":"additional","affiliation":[{"name":"National Laboratory of Radar Signal Processing, Xidian University, Xi\u2019an 710071, China"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"310","DOI":"10.1016\/j.sigpro.2015.05.019","article-title":"Robust stability analysis of H1-SGQKF and its application to transfer alignment","volume":"117","author":"Chen","year":"2015","journal-title":"Signal Process."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"338","DOI":"10.1109\/TGRS.2011.2158224","article-title":"Near-space vehicle-borne SAR with reflection-antenna for high-resolution and wide-swath remote sensing","volume":"50","author":"Wang","year":"2012","journal-title":"IEEE Trans.
