However, it is quite often in practical engineering that circular and noncircular signals appear in the same time. To effectively detect DOA of signals in such circumstances, we propose a novel algorithm. Firstly, using received data and its conjugate, we can detect more signals because of the doubled array aperture. Secondly, through unitary transform and multistage Wiener filter (MSWF) technology, we can obtain the noise subspace of array without performing eigendecomposition. Finally, by employing the improved MUSIC algorithm,we can acquire the DOA of the mixed circular and noncircular signals through two-stage search. Simulation results clearly demonstrate the effectiveness of the proposed algorithm.<\/jats:p>","DOI":"10.1155\/2014\/206146","type":"journal-article","created":{"date-parts":[[2014,10,1]],"date-time":"2014-10-01T17:01:37Z","timestamp":1412182897000},"page":"1-7","source":"Crossref","is-referenced-by-count":2,"title":["Fast Method for DOA Estimation with Circular and Noncircular Signals Mixed Together"],"prefix":"10.1155","volume":"2014","author":[{"given":"Yaoping","family":"Zeng","sequence":"first","affiliation":[{"name":"School of Marine Science and Technology, Northwestern Polytechnical University, Xi\u2019an 710072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yixin","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Marine Science and Technology, Northwestern Polytechnical University, Xi\u2019an 710072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guangyue","family":"Lu","sequence":"additional","affiliation":[{"name":"School of Communication and Information Engineering, Xi\u2019an University of Posts and Telecommunications, Xi\u2019an 710121, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qiongdan","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Electronics and Information, Northwestern Polytechnical University, Xi\u2019an 710072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"98","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1109\/79.526899"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1155\/2014\/241469"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.5402\/2011\/751670"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1155\/2014\/914327"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1155\/2010\/450487"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1016\/S0165-1684(01)00071-8"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2006.873505"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2004.826170"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2008.924143"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2011.2157499"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1109\/TAES.2012.6237619"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2007.916123"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1109\/18.737524"}],"container-title":["Journal of Electrical and Computer Engineering"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2014\/206146.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2014\/206146.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2014\/206146.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,8,18]],"date-time":"2016-08-18T09:44:08Z","timestamp":1471513448000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/jece\/2014\/206146\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014]]},"references-count":13,"alternative-id":["206146","206146"],"URL":"https:\/\/doi.org\/10.1155\/2014\/206146","relation":{},"ISSN":["2090-0147","2090-0155"],"issn-type":[{"value":"2090-0147","type":"print"},{"value":"2090-0155","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014]]}}}
