A pulse train with the random and sparse transmitting time is transmitted. The received signals after matched filtering can be viewed as randomly sparse sampling from the traditional fixed-pulse repetition frequency (PRF) echo signals. The whole target echo could be reconstructed via CS recovery algorithms. Through refining the sensing matrix, which is equivalent to increase the sampling frequency of target characteristic, the Doppler unambiguous range is enlarged. In particular, Complex Approximate Message Passing (CAMP) algorithm is developed to estimate the unambiguity Doppler frequency. Cramer-Rao lower bound expressions are derived for the frequency. Numerical simulations validate the effectiveness of the proposed method. Finally, compared with traditional methods, the proposed method only requires transmitting a few sparse probing pulses to achieve a larger Doppler frequency unambiguous range and can also reduce the consumption of the radar time resources.<\/jats:p>","DOI":"10.1155\/2015\/251849","type":"journal-article","created":{"date-parts":[[2015,5,11]],"date-time":"2015-05-11T21:05:18Z","timestamp":1431378318000},"page":"1-8","source":"Crossref","is-referenced-by-count":0,"title":["Doppler Ambiguity Resolution Based on Random Sparse Probing Pulses"],"prefix":"10.1155","volume":"2015","author":[{"given":"Yunjian","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Information Science and Engineering, Xiamen University, Fujian 361005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhenmiao","family":"Deng","sequence":"additional","affiliation":[{"name":"School of Information Science and Engineering, Xiamen University, Fujian 361005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianghong","family":"Shi","sequence":"additional","affiliation":[{"name":"School of Information Science and Engineering, Xiamen University, Fujian 361005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Linmei","family":"Ye","sequence":"additional","affiliation":[{"name":"School of Information Science and Engineering, Xiamen University, Fujian 361005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maozhong","family":"Fu","sequence":"additional","affiliation":[{"name":"School of Information Science and Engineering, Xiamen University, Fujian 361005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chen","family":"Zhao","sequence":"additional","affiliation":[{"name":"Faculty of Science, University of Auckland, Auckland 1052, New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1109\/7.599236"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2009.2025079"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1109\/tsp.2010.2066974"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/jsen.2011.2173482"},{"issue":"2","key":"5","first-page":"97","volume":"38","year":"2009","journal-title":"Journal of University of Electronic Science and Technology of China"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.3724\/sp.j.1146.2011.00073"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1049\/el.2011.1293"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1137\/S1064827596304010"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1016\/j.acha.2012.08.003"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1109\/tit.2013.2252232"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0909892106"},{"issue":"1","key":"17","doi-asserted-by":"crossref","first-page":"267","DOI":"10.1111\/j.2517-6161.1996.tb02080.x","volume":"58","year":"1996","journal-title":"Journal of the Royal Statistical Society, Series B: Methodological"},{"key":"23","doi-asserted-by":"publisher","DOI":"10.1109\/JSTSP.2009.2039176"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1109\/tsp.2012.2193392"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2011.2177834"}],"container-title":["Journal of Electrical and Computer Engineering"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2015\/251849.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2015\/251849.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2015\/251849.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,6,8]],"date-time":"2024-06-08T22:48:57Z","timestamp":1717886937000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/jece\/2015\/251849\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015]]},"references-count":15,"alternative-id":["251849","251849"],"URL":"https:\/\/doi.org\/10.1155\/2015\/251849","relation":{},"ISSN":["2090-0147","2090-0155"],"issn-type":[{"value":"2090-0147","type":"print"},{"value":"2090-0155","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015]]}}}
