However, migrating insects usually have small radar-cross-section (RCS) and are accompanied by maneuvering. The current radar detection algorithms mainly have contradictions in detection performance and computational complexity. So it is difficult for traditional radar detection algorithms to detect them effectively. Hence, a novel coherent integration detection algorithm based on dynamic programming (DP) and fractional Fourier transforming (FrFT) is proposed. By combining the advantages of DP and FrFT, the proposed DP-FrFT method can quickly search the target track, and simultaneously perform parameters estimation and motion compensation, achieving high integration gain with relatively low time consumption. The high efficiency of the method is verified with a large number of simulations and sufficient field experiments.<\/jats:p>","DOI":"10.3390\/rs12193238","type":"journal-article","created":{"date-parts":[[2020,10,5]],"date-time":"2020-10-05T08:35:57Z","timestamp":1601886957000},"page":"3238","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["A Novel Radar Detection Method for Sensing Tiny and Maneuvering Insect Migrants"],"prefix":"10.3390","volume":"12","author":[{"given":"Rui","family":"Wang","sequence":"first","affiliation":[{"name":"School of Information and Electronics, The Beijing Institute of Technology, Beijing 100081, China"},{"name":"The Advanced Technology Research Institute, The Beijing Institute of Technology, Jinan 250300, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiong","family":"Cai","sequence":"additional","affiliation":[{"name":"School of Information and Electronics, The Beijing Institute of Technology, Beijing 100081, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cheng","family":"Hu","sequence":"additional","affiliation":[{"name":"School of Information and Electronics, The Beijing Institute of Technology, Beijing 100081, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chao","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Information and Electronics, The Beijing Institute of Technology, Beijing 100081, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tianran","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Information and Electronics, The Beijing Institute of Technology, Beijing 100081, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,10,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"113","DOI":"10.1641\/B570206","article-title":"What is migration?","volume":"57","author":"Dingle","year":"2007","journal-title":"Bioscience"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1584","DOI":"10.1126\/science.aah4379","article-title":"Mass seasonal bioflows of high-flying insect migrants","volume":"354","author":"Hu","year":"2016","journal-title":"Science"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"6","DOI":"10.1186\/s40317-018-0151-5","article-title":"Passive kHz lidar for the quantification of insect activity and dispersal","volume":"6","author":"Jansson","year":"2018","journal-title":"Anim.
