The complexity of these systems requires performing extensive measurement campaigns in order to test their performance and detection capabilities. However, UAV flights are limited by weather conditions and battery autonomy. To overcome these problems, this contribution presents a portable and easily-deployable measurement setup which can be used as a testbed for the assessment of the capabilities of the airborne system. In particular, the proposed portable measurement setup replicates fairly well the conditions faced by the airborne system, which can hardly be reproduced in indoor GPR measurement facilities. Three validation examples are presented: the first two analyze the capability of the measurement setup to conduct experiments in different scenarios (loamy and sandy soils). The third example focuses on the problem of antenna phase center displacement with frequency and its impact on GPR imaging, proposing a simple technique to correct it.<\/jats:p>","DOI":"10.3390\/rs12111833","type":"journal-article","created":{"date-parts":[[2020,6,9]],"date-time":"2020-06-09T09:16:14Z","timestamp":1591694174000},"page":"1833","source":"Crossref","is-referenced-by-count":19,"title":["Portable and Easily-Deployable Air-Launched GPR Scanner"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8935-1912","authenticated-orcid":false,"given":"Mar\u00eda","family":"Garc\u00eda-Fern\u00e1ndez","sequence":"first","affiliation":[{"name":"Area of Signal Theory and Communications, University of Oviedo, 33201\u201333212 Gijon, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3625-4515","authenticated-orcid":false,"given":"Yuri","family":"\u00c1lvarez L\u00f3pez","sequence":"additional","affiliation":[{"name":"Area of Signal Theory and Communications, University of Oviedo, 33201\u201333212 Gijon, Spain"}]},{"given":"Alessandro","family":"De Mitri","sequence":"additional","affiliation":[{"name":"Department of Geoscience, University of Pisa, 56121\u201356128 Pisa, Italy"}]},{"given":"David","family":"Castrillo Mart\u00ednez","sequence":"additional","affiliation":[{"name":"Area of Signal Theory and Communications, University of Oviedo, 33201\u201333212 Gijon, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9286-4372","authenticated-orcid":false,"given":"Guillermo","family":"\u00c1lvarez-Narciandi","sequence":"additional","affiliation":[{"name":"Area of Signal Theory and Communications, University of Oviedo, 33201\u201333212 Gijon, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7959-2114","authenticated-orcid":false,"given":"Fernando","family":"Las-Heras Andr\u00e9s","sequence":"additional","affiliation":[{"name":"Area of Signal Theory and Communications, University of Oviedo, 33201\u201333212 Gijon, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2020,6,5]]},"reference":[{"key":"ref_1","unstructured":"Jol, H.M.
