This paper presents a composite backscattering model of the sea surface and conductive and dielectric ships under different sea conditions. The ship scattering is calculated using the equivalent edge electromagnetic current (EEC) theory. The scattering of the sea surface with wedge-like breaking waves is calculated using the capillary wave phase perturbation method combined with the multi-path scattering method. The coupling scattering between ship and sea surface is obtained using the modified four-path model. The results reveal that the backscattering RCS of the dielectric target is significantly reduced compared with the conducting target. Furthermore, the composite backscattering of the sea surface and ship increases significantly in both HH and VV polarizations when considering the effect of breaking waves under high sea conditions at low grazing angles in the upwind direction, especially for HH polarization. This research offers valuable insights into optimizing radar detection of marine targets in varying sea conditions.<\/jats:p>","DOI":"10.3390\/s23104904","type":"journal-article","created":{"date-parts":[[2023,5,19]],"date-time":"2023-05-19T10:08:55Z","timestamp":1684490935000},"page":"4904","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Composite Backscatter Characteristics of Conductive\/Dielectric Ships and Sea Surfaces with Breaking Waves under High Sea Conditions"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6229-3342","authenticated-orcid":false,"given":"Xiaoxiao","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Electronic Engineering, Xi\u2019an University of Posts & Telecommunications, Xi\u2019an 710121, China"}]},{"given":"Xiang","family":"Su","sequence":"additional","affiliation":[{"name":"China Academy of Space Technology, Xi\u2019an 710100, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3354-7275","authenticated-orcid":false,"given":"Zhensen","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Physics, Xidian University, Xi\u2019an 710071, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,19]]},"reference":[{"key":"ref_1","first-page":"69","article-title":"A review on the research of composite electromagnetic scattering from target and rough surface","volume":"35","author":"Guo","year":"2020","journal-title":"Chin.
