The azimuth echo can be characterized as a multi-component polynomial phase signal (PPS) after the translational compensation, and the high quality ISAR images can be obtained by the parameters estimation of it combined with the Range-Instantaneous-Doppler (RID) technique. In this paper, a novel parameters estimation algorithm of the multi-component PPS with order three (cubic phase signal-CPS) based on the modified discrete polynomial-phase transform (MDPT) is proposed, and the corresponding new ISAR imaging algorithm is presented consequently. This algorithm is efficient and accurate to generate a focused ISAR image, and the results of real data demonstrate the effectiveness of it.<\/jats:p>","DOI":"10.3390\/s150922401","type":"journal-article","created":{"date-parts":[[2015,9,3]],"date-time":"2015-09-03T10:57:07Z","timestamp":1441277827000},"page":"22401-22418","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["ISAR Imaging of Maneuvering Targets Based on the Modified Discrete Polynomial-Phase Transform"],"prefix":"10.3390","volume":"15","author":[{"given":"Yong","family":"Wang","sequence":"first","affiliation":[{"name":"Research Institute of Electronic Engineering Technology, Harbin Institute of Technology, Harbin 150001, China"}]},{"given":"Ali","family":"Abdelkader","sequence":"additional","affiliation":[{"name":"Research Institute of Electronic Engineering Technology, Harbin Institute of Technology, Harbin 150001, China"}]},{"given":"Bin","family":"Zhao","sequence":"additional","affiliation":[{"name":"Research Institute of Electronic Engineering Technology, Harbin Institute of Technology, Harbin 150001, China"}]},{"given":"Jinxiang","family":"Wang","sequence":"additional","affiliation":[{"name":"Research Institute of Electronic Engineering Technology, Harbin Institute of Technology, Harbin 150001, China"}]}],"member":"1968","published-online":{"date-parts":[[2015,9,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"213","DOI":"10.1049\/ip-rsn:20030670","article-title":"Application of adaptive joint time-frequency algorithm for focusing distorted ISAR images from simulated and measured radar data","volume":"150","author":"Thayaparan","year":"2003","journal-title":"IEE Proc.
