However, to make full use of an ISAR image in target detection and recognition, we need to rescale the image in a homogeneous range and cross\u2010range domain, and further, to estimate the effective rotational velocity (RV) of the target. A precise ISAR image cross\u2010range scaling method is proposed. A candidate RV is obtained based on the bisection method. Then, the effective rotation angle (RA) between two sequential rescaled images is characterised by the RA between the major axes of the images. These axes are extracted by principle component analysis (PCA). A precise estimation of the RV is obtained through iterative PCA and bisection. Simulated and real data experimental results validate the effectiveness of the proposed method.<\/jats:p>","DOI":"10.1049\/sil2.12034","type":"journal-article","created":{"date-parts":[[2021,3,25]],"date-time":"2021-03-25T22:54:21Z","timestamp":1616712861000},"page":"314-322","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["A modified ISAR cross\u2010range scaling method based on iterative principle component analysis"],"prefix":"10.1049","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6098-9004","authenticated-orcid":false,"given":"Xingyu","family":"He","sequence":"first","affiliation":[{"name":"Air Traffic Control and Navigation College Air Force Engineering University  Xi'an Shaanxi China"}]},{"given":"Ningning","family":"Tong","sequence":"additional","affiliation":[{"name":"Air and Missile Defense College Air Force Engineering University  Xi'an Shaanxi China"}]},{"given":"Tao","family":"Liu","sequence":"additional","affiliation":[{"name":"Teaching and Research Guarantee Center Air Force Engineering University  Xi'an Shaanxi China"}]}],"member":"265","published-online":{"date-parts":[[2021,3,25]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/TAES.2014.120535"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1049\/iet-spr.2017.0366"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1109\/TGRS.2013.2251348"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1049\/el.2014.3368"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1109\/TAES.2017.2668058"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1109\/TAP.2015.2408337"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1109\/TAES.2018.2807283"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1109\/TGRS.2019.2911686"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/9781118178072"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.sigpro.2016.12.002"},{"key":"e_1_2_8_12_1","first-page":"1822","volume-title":"Proceedings of Signal Processing, 5th International Conference on WCCC\u2010ICSP","author":"Jiang Z.","year":"2000"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1109\/TAES.2008.4517004"},{"issue":"3","key":"e_1_2_8_14_1","first-page":"1","article-title":"A compensation method for ununiform sampling of rotating angle in ISAR imaging","volume":"18","author":"Qiu X.
