Firstly, Sentinel-1 and the designed system are introduced. Then, signal model, signal pre-processing methods, and effective target imaging methods are presented. At last, various experiment results of target imaging obtained at different locations are shown to validate the developed system and the proposed methods. It was found that targets in a range of several kilometers can be well imaged.<\/jats:p>","DOI":"10.3390\/rs14010221","type":"journal-article","created":{"date-parts":[[2022,1,9]],"date-time":"2022-01-09T23:06:15Z","timestamp":1641769575000},"page":"221","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["SDR-Implemented Passive Bistatic SAR System Using Sentinel-1 Signal and Its Experiment Results"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4205-538X","authenticated-orcid":false,"given":"Weike","family":"Feng","sequence":"first","affiliation":[{"name":"Early Warning and Detection Department, Air Force Engineering University, Xi\u2019an 710051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4888-7133","authenticated-orcid":false,"given":"Jean-Michel","family":"Friedt","sequence":"additional","affiliation":[{"name":"Time & Frequency Department, FEMTO-ST, 25030 Besancon, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5960-8377","authenticated-orcid":false,"given":"Pengcheng","family":"Wan","sequence":"additional","affiliation":[{"name":"Early Warning and Detection Department, Air Force Engineering University, Xi\u2019an 710051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,4]]},"reference":[{"key":"ref_1","unstructured":"Griffiths, H.D., and Baker, C.J.
