Recently, several design methods have been developed to generate phased-coded sequences satisfying specific aperiodic or periodic autocorrelation sidelobe level metrics. In this paper, based on the majorization\u2013minimization strategy and the squared iterative acceleration scheme, we propose a method to generate sequences with the periodic weighted integrated sidelobe level metric. Numerical simulations illustrate that the proposed method can effectively suppress the periodic autocorrelation sidelobe levels in specific time lags. Compared with other sequence design methods satisfying the periodic weighted integrated sidelobe level metric, our method improves the computational efficiency significantly. In addition, the proposed sequence demonstrates better matched filter performance in specific range intervals compared with its counterpart. The results suggest that the method could be applied as a valid and real-time design method for transmitted signals of active sonars.<\/jats:p>","DOI":"10.3390\/s20174659","type":"journal-article","created":{"date-parts":[[2020,8,19]],"date-time":"2020-08-19T09:22:31Z","timestamp":1597828951000},"page":"4659","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["A Phase-Coded Sequence Design Method for Active Sonar"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8795-4389","authenticated-orcid":false,"given":"Chengyu","family":"Guan","sequence":"first","affiliation":[{"name":"College of Meteorology and Oceanology, National University of Defense Technology Changsha, Changsha 410000, China"}]},{"given":"Zemin","family":"Zhou","sequence":"additional","affiliation":[{"name":"College of Meteorology and Oceanology, National University of Defense Technology Changsha, Changsha 410000, China"}]},{"given":"Xinwu","family":"Zeng","sequence":"additional","affiliation":[{"name":"College of Meteorology and Oceanology, National University of Defense Technology Changsha, Changsha 410000, China"}]}],"member":"1968","published-online":{"date-parts":[[2020,8,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2866","DOI":"10.1109\/TSP.2016.2535312","article-title":"Sequence Set Design with Good Correlation Properties Via Majorization-Minimization","volume":"64","author":"Song","year":"2016","journal-title":"IEEE Trans.
