Different from the conventional pulsed mode, the stop\u2010to\u2010go approximation is not valid in FMCW SAR. Thus, the typical SAR imaging methods need to be modified to adapt the continuous\u2010wave scheme in practical data processing. In this letter, a wavenumber domain algorithm (WDA) is derived and used for the FMCW SAR imaging under squint and high\u2010squint cases. With the help of the exact scene recovery ability of the proposed WDA, we can achieve the accurate recovery of the considered scene even when using the collected high\u2010squint data and hence obtain the well\u2010focused high\u2010resolution image of the considered scene. Experimental results with simulated and airborne data verify the effectiveness of the proposed method.<\/jats:p>","DOI":"10.1155\/2021\/5551674","type":"journal-article","created":{"date-parts":[[2021,4,2]],"date-time":"2021-04-02T16:05:05Z","timestamp":1617379505000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["High\u2010Squint FMCW SAR Imaging via Wavenumber Domain Algorithm"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9357-8412","authenticated-orcid":false,"given":"Hui","family":"Bi","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7560-5288","authenticated-orcid":false,"given":"Hao","family":"Li","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9012-9753","authenticated-orcid":false,"given":"Wei","family":"Liang","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2021,4,2]]},"reference":[{"volume-title":"Synthetic Aperture Radar: System and Signal Processing","year":"1991","author":"Curlander J.
