So, efficient radar signal processing techniques are needed to reduce it. In this way, nonlinear signal processing techniques based on neural networks (NNs) are used in the proposed clutter reduction system. The developed experiments show promising results characterized by different subjective (visual analysis of the processed radar images) and objective (clutter reduction, target enhancement and signal-to-clutter ratio improvement) criteria. Moreover, a deep study of the NN structure is done, where the low computational cost and the high processing speed of the proposed NN structure are emphasized.<\/jats:p>","DOI":"10.3390\/s90301913","type":"journal-article","created":{"date-parts":[[2009,3,16]],"date-time":"2009-03-16T12:57:00Z","timestamp":1237208220000},"page":"1913-1936","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["Sea Clutter Reduction and Target Enhancement by Neural Networks in a Marine Radar System"],"prefix":"10.3390","volume":"9","author":[{"given":"Ra\u00fal","family":"Vicen-Bueno","sequence":"first","affiliation":[{"name":"Signal Theory and Communications Department, Superior Politechnic School, University of Alcal\u00b4a, Alcal\u00b4a de Henares, 28805, Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rub\u00e9n","family":"Carrasco-\u00c1lvarez","sequence":"additional","affiliation":[{"name":"Signal Theory and Communications Department, Superior Politechnic School, University of Alcal\u00b4a, Alcal\u00b4a de Henares, 28805, Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manuel","family":"Rosa-Zurera","sequence":"additional","affiliation":[{"name":"Signal Theory and Communications Department, Superior Politechnic School, University of Alcal\u00b4a, Alcal\u00b4a de Henares, 28805, Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jos\u00e9 Carlos","family":"Nieto-Borge","sequence":"additional","affiliation":[{"name":"Signal Theory and Communications Department, Superior Politechnic School, University of Alcal\u00b4a, Alcal\u00b4a de Henares, 28805, Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2009,3,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"373","DOI":"10.1017\/S0373463307004298","article-title":"Automatic identification system (AIS): Data reliability and human error implications","volume":"60","author":"Wall","year":"2007","journal-title":"J.
