An accurate evaluation of this IM is of paramount importance in bridge engineering, both for designing safe and economical new bridges, and for the assessment of the existing ones. At the state of the art, the current procedure for the experimental assessment of the IM of a bridge relies upon the deployment of a sensor network. The aim of this article is to propose the use of a remote sensor, the interferometric radar, for assessing the IM without the deployment of any sensor on the bridge, with evident advantages in terms of cost, time and safety of the workers. Two different case studies of bridges in Northern Iran are reported. In both cases the interferometric radar has been demonstrated an effective and reliable measurement equipment for this kind of in-field assessment.<\/jats:p>","DOI":"10.3390\/rs11192207","type":"journal-article","created":{"date-parts":[[2019,9,23]],"date-time":"2019-09-23T03:26:32Z","timestamp":1569209192000},"page":"2207","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Experimental Dynamic Impact Factor Assessment of Railway Bridges through a Radar Interferometer"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3661-726X","authenticated-orcid":false,"given":"Massimiliano","family":"Pieraccini","sequence":"first","affiliation":[{"name":"Department of Information Engineering, University of Florence, Via Santa Marta, 3 50139 Firenze, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7285-4588","authenticated-orcid":false,"given":"Lapo","family":"Miccinesi","sequence":"additional","affiliation":[{"name":"Department of Information Engineering, University of Florence, Via Santa Marta, 3 50139 Firenze, Italy"}]},{"given":"Ali","family":"Abdorazzagh Nejad","sequence":"additional","affiliation":[{"name":"GeoRAYAN Ltd.
