In the last years, novel architectures for safe and fast detection, such as those based on GPR systems onboard Unmanned Aerial Vehicles (UAVs), have been proposed. Furthermore, improvements in GPR hardware and signal processing techniques have resulted in a more efficient detection. This contribution presents an experimental validation of a hybrid Forward-Looking\u2013Down-Looking GPR architecture. The main goal of this architecture is to combine advantages of both GPR architectures: reduction of clutter coming from the ground surface in the case of Forward-Looking GPR (FLGPR), and greater dynamic range in the case of Down-Looking GPR (DLGPR). Compact radar modules working in the lower SHF frequency band have been used for the validation of the hybrid architecture, which involved realistic targets.<\/jats:p>","DOI":"10.3390\/rs13061206","type":"journal-article","created":{"date-parts":[[2021,3,22]],"date-time":"2021-03-22T16:55:07Z","timestamp":1616432107000},"page":"1206","source":"Crossref","is-referenced-by-count":6,"title":["Analysis and Validation of a Hybrid Forward-Looking Down-Looking Ground Penetrating Radar Architecture"],"prefix":"10.3390","volume":"13","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, 33003 Oviedo, 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, 33003 Oviedo, 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, 33003 Oviedo, 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, 33003 Oviedo, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,22]]},"reference":[{"unstructured":"Jol, H.M.
