In this paper, an Inverse Synthetic Aperture Radar (ISAR) image feature suppression method based on arbitrary phase encoding (APE) is proposed. The parameter design criterion is further analyzed. Through the nonperiodic segmented coding and modulation of the imaging signal in fast and slow time domains, the modulated signal produces a two-dimensional suppression region with uniform energy distribution in the ISAR image. Simulations via the measured Yak-42 aircraft data have verified the effectiveness of the proposed method for target feature control. Compared to binary phase modulation jamming, the APE method with a phase modulation accuracy of 1 degree can achieve the same jamming effect while reducing the jamming power requirement by 3 dB. By optimizing with the proposed method, the image entropy of the interfered image increases by 1.1 to 1.5 compared to the original image.<\/jats:p>","DOI":"10.3390\/rs16213960","type":"journal-article","created":{"date-parts":[[2024,10,24]],"date-time":"2024-10-24T09:11:47Z","timestamp":1729761107000},"page":"3960","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Novel ISAR Image Feature Suppression Method Based on Arbitrary Phase Encoding"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-0173-6519","authenticated-orcid":false,"given":"Yanfeng","family":"Wang","sequence":"first","affiliation":[{"name":"State Key Laboratory of Complex Electromagnetic Environmental Effects on Electronics and Information System, National University of Defense Technology, Changsha 410003, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9998-2301","authenticated-orcid":false,"given":"Qihua","family":"Wu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Complex Electromagnetic Environmental Effects on Electronics and Information System, National University of Defense Technology, Changsha 410003, China"}]},{"given":"Xiaobin","family":"Liu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Complex Electromagnetic Environmental Effects on Electronics and Information System, National University of Defense Technology, Changsha 410003, China"}]},{"given":"Zhiming","family":"Xu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Complex Electromagnetic Environmental Effects on Electronics and Information System, National University of Defense Technology, Changsha 410003, China"}]},{"given":"Feng","family":"Zhao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Complex Electromagnetic Environmental Effects on Electronics and Information System, National University of Defense Technology, Changsha 410003, China"}]},{"given":"Shunping","family":"Xiao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Complex Electromagnetic Environmental Effects on Electronics and Information System, National University of Defense Technology, Changsha 410003, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Zou, X., Jin, G., He, F., and Zhang, Y.
