Notice that the problem essentially resolves the high sidelobes of the non-grid multiple scatterers after locating positions; we proposed a novel iterative algorithm based on an adaptive pulse compression algorithm on the basis of an off-grid position estimation. First, the grid offsets of the multiple scattering points through decoherence and super-resolution techniques are estimated by employing an enhanced MUSIC algorithm. Then, an optimization model is constructed for the non-grid multiple scattering points of the target. Finally, a sidelobe suppression algorithm based on the minimum mean square error (MMSE) criterion is presented. Numerical results reveal that the proposed algorithm can achieve better estimation performance on the offsets of the non-grid multiple scattering points, while it suppresses range sidelobes effectively.<\/jats:p>","DOI":"10.3390\/rs15194811","type":"journal-article","created":{"date-parts":[[2023,10,3]],"date-time":"2023-10-03T07:28:29Z","timestamp":1696318109000},"page":"4811","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Range Sidelobe Iterative Suppression Algorithm for Extended Target with Non-Grid Multiple Scattering Points"],"prefix":"10.3390","volume":"15","author":[{"given":"Jing","family":"Xu","sequence":"first","affiliation":[{"name":"The School of Electronic and Information Engineering, Nanjing University of Aeronautics and Astronautics, Nanjing 210000, China"}]},{"given":"Yanan","family":"Zhang","sequence":"additional","affiliation":[{"name":"The School of Electronic and Information Engineering, Nanjing University of Aeronautics and Astronautics, Nanjing 210000, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6464-6431","authenticated-orcid":false,"given":"Jindong","family":"Zhang","sequence":"additional","affiliation":[{"name":"The School of Electronic and Information Engineering, Nanjing University of Aeronautics and Astronautics, Nanjing 210000, China"}]},{"given":"Jiarui","family":"Chen","sequence":"additional","affiliation":[{"name":"The 723 Institute of CSSC, Zhenjiang 212000, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,3]]},"reference":[{"key":"ref_1","unstructured":"Jiangbo, L., Hongsheng, Y., Dongbo, H., and Minh, N.D.
