In this paper, we propose a novel method based on compressed sensing (CS) to solve micro-Doppler ambiguity. According to the RIP requirement, a sparse probing pulse train with its transmitting time random is designed. After matched filtering, the slow-time echo signals of the micromotion target can be viewed as randomly sparse sampling of Doppler spectrum. Select several successive pulses to form a short-time window and the CS sensing matrix can be built according to the time stamps of these pulses. Then performing Orthogonal Matching Pursuit (OMP), the unambiguous micro-Doppler spectrum can be obtained. The proposed algorithm is verified using the echo signals generated according to the theoretical model and the signals with micro-Doppler signature produced using the commercial electromagnetic simulation software FEKO.<\/jats:p>","DOI":"10.1155\/2015\/864508","type":"journal-article","created":{"date-parts":[[2015,8,17]],"date-time":"2015-08-17T17:05:04Z","timestamp":1439831104000},"page":"1-7","source":"Crossref","is-referenced-by-count":4,"title":["Micro-Doppler Ambiguity Resolution Based on Short-Time Compressed Sensing"],"prefix":"10.1155","volume":"2015","author":[{"given":"Jing-bo","family":"Zhuang","sequence":"first","affiliation":[{"name":"School of Information Science and Engineering, Xiamen University, Xiamen 361005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhen-miao","family":"Deng","sequence":"additional","affiliation":[{"name":"School of Information Science and Engineering, Xiamen University, Xiamen 361005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi-shan","family":"Ye","sequence":"additional","affiliation":[{"name":"School of Information Science and Engineering, Xiamen University, Xiamen 361005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi-xiong","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Information Science and Engineering, Xiamen University, Xiamen 361005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yan-yong","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Information Science and Engineering, Xiamen University, Xiamen 361005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"doi-asserted-by":"publisher","key":"1","DOI":"10.1049\/iet-spr.2009.0093"},{"doi-asserted-by":"publisher","key":"2","DOI":"10.1049\/iet-spr.2009.0044"},{"doi-asserted-by":"publisher","key":"3","DOI":"10.1049\/iet-spr.2009.0094"},{"doi-asserted-by":"publisher","key":"4","DOI":"10.1016\/j.jfranklin.2008.01.003"},{"doi-asserted-by":"publisher","key":"5","DOI":"10.1109\/tgrs.2013.2269138"},{"doi-asserted-by":"publisher","key":"6","DOI":"10.1109\/tgrs.2013.2271706"},{"doi-asserted-by":"publisher","key":"7","DOI":"10.1016\/j.dsp.2011.10.009"},{"issue":"4","key":"8","doi-asserted-by":"crossref","first-page":"1496","DOI":"10.1109\/TAES.2006.314590","volume":"42","year":"2006","journal-title":"IEEE Transactions on Aerospace and Electronic Systems"},{"doi-asserted-by":"publisher","key":"9","DOI":"10.1109\/TAES.2013.6494410"},{"doi-asserted-by":"publisher","key":"10","DOI":"10.1049\/el.2011.1293"},{"doi-asserted-by":"publisher","key":"11","DOI":"10.3724\/sp.j.1146.2011.00073"},{"doi-asserted-by":"publisher","key":"12","DOI":"10.1109\/tap.2013.2291893"},{"doi-asserted-by":"publisher","key":"13","DOI":"10.1109\/MSP.2011.942308"},{"doi-asserted-by":"publisher","key":"14","DOI":"10.1016\/j.acha.2012.08.003"},{"doi-asserted-by":"publisher","key":"16","DOI":"10.1073\/pnas.0437847100"},{"issue":"5","key":"17","first-page":"675","volume":"28","year":"2012","journal-title":"Signal Processing"},{"doi-asserted-by":"publisher","key":"18","DOI":"10.1109\/tsp.2012.2193392"}],"container-title":["Journal of Electrical and Computer Engineering"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2015\/864508.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2015\/864508.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2015\/864508.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,23]],"date-time":"2017-06-23T13:47:34Z","timestamp":1498225654000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/jece\/2015\/864508\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015]]},"references-count":17,"alternative-id":["864508","864508"],"URL":"https:\/\/doi.org\/10.1155\/2015\/864508","relation":{},"ISSN":["2090-0147","2090-0155"],"issn-type":[{"type":"print","value":"2090-0147"},{"type":"electronic","value":"2090-0155"}],"subject":[],"published":{"date-parts":[[2015]]}}}
