However, little research has been done to install the millimeter-wave radar on the top of a road for detecting road traffic flow at a downward looking direction. In this paper, the vehicle parameters, including the distance, angle and radar cross-section energy, are collected by practical experiments in the aforementioned application scenario. The data features are analyzed from the dimensions of single parameter sampling characteristics and multi-parameter relationships. Further, the correlations of different parameter series are given using the grey correlation analysis method. For millimeter-wave radar used in the traffic flow detection, our work can definitely provide significant support for further intelligent transportation applications, such as vehicle trajectory tracking, traffic flow estimation and traffic event identification.<\/jats:p>","DOI":"10.3390\/s18092756","type":"journal-article","created":{"date-parts":[[2018,8,22]],"date-time":"2018-08-22T03:42:37Z","timestamp":1534909357000},"page":"2756","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Data Feature Analysis of Non-Scanning Multi Target Millimeter-Wave Radar in Traffic Flow Detection Applications"],"prefix":"10.3390","volume":"18","author":[{"given":"Haiqing","family":"Liu","sequence":"first","affiliation":[{"name":"College of Transportation, Shandong University of Science and Technology, Qingdao 266000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Na","family":"Li","sequence":"additional","affiliation":[{"name":"College of Electronics, Communication and Physics, Shandong University of Science and Technology, Qingdao 266000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Deyong","family":"Guan","sequence":"additional","affiliation":[{"name":"College of Transportation, Shandong University of Science and Technology, Qingdao 266000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laxmisha","family":"Rai","sequence":"additional","affiliation":[{"name":"College of Electronics, Communication and Physics, Shandong University of Science and Technology, Qingdao 266000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,8,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"31794","DOI":"10.3390\/s151229889","article-title":"Sensing traffic density combining V2V and V2I wireless communications","volume":"15","author":"Sanguesa","year":"2015","journal-title":"Sensors"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Liu, H.Q., Rai, L., Wang, J.C., and Ren, C.X.
