When measuring with only one radar device, the so-called Interpretation Error (EI) considerably rises. When using two radars, it is possible to simultaneously determine, for example, vertical and longitudinal displacements and to eliminate the Interpretation Error. The aim of the article is to establish a suitable strategy for determining dynamic and quasi-static response of bridge structures based on the accuracy analysis of measurement by two radars. The necessary theory for displacements determination by means of two radar devices is presented. This is followed by an analysis of errors when measuring with only one radar. For the first time in the literature, mathematical formulas are derived here for determining the accuracy of the resulting displacements by simultaneous measurement with two radars. The practical examples of bridge structures displacements determination by measuring with two radar devices in the field are presented. The key contribution of the paper is the possibility to estimate and plan in advance the achievable accuracy of the resulting displacements for the given radar configurations in relation to the bridge structure.<\/jats:p>","DOI":"10.3390\/rs15030837","type":"journal-article","created":{"date-parts":[[2023,2,3]],"date-time":"2023-02-03T03:36:57Z","timestamp":1675395417000},"page":"837","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Accuracy Analysis and Appropriate Strategy for Determining Dynamic and Quasi-Static Bridge Structural Response Using Simultaneous Measurements with Two Real Aperture Ground-Based Radars"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3703-711X","authenticated-orcid":false,"given":"Milan","family":"Talich","sequence":"first","affiliation":[{"name":"The Czech Academy of Sciences, Institute of Information Theory and Automation, Pod Vod\u00e1renskou V\u011b\u017e\u00ed 4, 182 00 Prague, Czech Republic"}]},{"given":"Jan","family":"Havrlant","sequence":"additional","affiliation":[{"name":"The Czech Academy of Sciences, Institute of Information Theory and Automation, Pod Vod\u00e1renskou V\u011b\u017e\u00ed 4, 182 00 Prague, Czech Republic"}]},{"given":"Lubom\u00edr","family":"Soukup","sequence":"additional","affiliation":[{"name":"The Czech Academy of Sciences, Institute of Information Theory and Automation, Pod Vod\u00e1renskou V\u011b\u017e\u00ed 4, 182 00 Prague, Czech Republic"}]},{"given":"Tom\u00e1\u0161","family":"Plach\u00fd","sequence":"additional","affiliation":[{"name":"Department of Mechanics, Faculty of Civil Engineering, Czech Technical University in Prague, Th\u00e1kurova 7, 166 29 Prague, Czech Republic"}]},{"given":"Michal","family":"Pol\u00e1k","sequence":"additional","affiliation":[{"name":"Department of Mechanics, Faculty of Civil Engineering, Czech Technical University in Prague, Th\u00e1kurova 7, 166 29 Prague, Czech Republic"}]},{"given":"Filip","family":"Anto\u0161","sequence":"additional","affiliation":[{"name":"The Czech Academy of Sciences, Institute of Information Theory and Automation, Pod Vod\u00e1renskou V\u011b\u017e\u00ed 4, 182 00 Prague, Czech Republic"}]},{"given":"Pavel","family":"Ryj\u00e1\u010dek","sequence":"additional","affiliation":[{"name":"Department of Steel and Timber Structures, Faculty of Civil Engineering, Czech Technical University in Prague, Th\u00e1kurova 7, 166 29 Prague, Czech Republic"}]},{"given":"Vojt\u011bch","family":"Stan\u010d\u00edk","sequence":"additional","affiliation":[{"name":"Department of Steel and Timber Structures, Faculty of Civil Engineering, Czech Technical University in Prague, Th\u00e1kurova 7, 166 29 Prague, Czech Republic"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"571","DOI":"10.1016\/j.engstruct.2016.08.006","article-title":"A bridge safety monitoring system for prestressed composite box-girder bridges with corrugated steel webs based on in-situ loading experiments and a long-term monitoring database","volume":"126","author":"Sung","year":"2016","journal-title":"Eng.
