These are in result of the application of various radar image-treatment techniques, with which we wanted to carry out a non-invasive exploration of areas of the archaeological site of Clunia (Burgos, Spain). These areas were analyzed and contrasted with other sources from high-resolution multispectral images (TripleSat), or from digital surface models obtained from Laser Imaging Detection and Ranging (LiDAR) data from the National Plan for Aerial Orthophotography (PNOA), and treated with image enhancement functions (Relief Visualization Tools (RVT)). Moreover, they were compared with multispectral images created from the Infrared Red Blue (IRRB) data contained in the same LiDAR points.<\/jats:p>","DOI":"10.3390\/rs13122344","type":"journal-article","created":{"date-parts":[[2021,6,15]],"date-time":"2021-06-15T21:24:29Z","timestamp":1623792269000},"page":"2344","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Tests with SAR Images of the PAZ Platform Applied to the Archaeological Site of Clunia (Burgos, Spain)"],"prefix":"10.3390","volume":"13","author":[{"given":"Ignacio","family":"Fiz","sequence":"first","affiliation":[{"name":"Catalan Institute of Classical Archaeology (ICAC), Rovira i Virgili University (URV), 43001 Tarragona, Spain"},{"name":"Department of History and Art History, Rovira i Virgili University (URV), 43002 Tarragona, Spain"}]},{"given":"Rosa","family":"Cuesta","sequence":"additional","affiliation":[{"name":"Unidad de Cultura-Monasterio de San Agustin, Diputaci\u00f3n de Burgos, 09002 Burgos, Spain"}]},{"given":"Eva","family":"Subias","sequence":"additional","affiliation":[{"name":"Department of History and Art History, Rovira i Virgili University (URV), 43002 Tarragona, Spain"}]},{"given":"Pere Manel","family":"Martin","sequence":"additional","affiliation":[{"name":"Department of History and Art History, Rovira i Virgili University (URV), 43002 Tarragona, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,15]]},"reference":[{"key":"ref_1","first-page":"123","article-title":"Hydraulic and urban management during Roman times based on GIS and remote sensing analysis (Clunia, Spain)","volume":"29","author":"Cuesta","year":"2019","journal-title":"Rev.
