Different techniques developed before, such as stereo-radargrammetry, have been experienced from space only in very limiting geometries and time series, and, hence, branded as less accurate. However, novel formation flying configurations achievable by modern spacecraft allow fulfillment of SAR missions able to produce pairs of monostatic-bistatic images gathered simultaneously, with programmed looking angles. Hence it is possible to achieve large antenna separations, adequate for exploiting to the utmost the stereoscopic effect, and to make negligible time decorrelation, a strong liming factor for repeat-pass stereo-radargrammetric techniques. This paper reports on design of a monostatic-bistatic mission, in terms of orbit and pointing geometry, and taking into account present generation SAR and technology for accurate relative navigation. Performances of different methods for monostatic-bistatic stereo-radargrammetry are then evaluated, showing the possibility to determine the local surface relief with a metric accuracy over a wide range of Earth latitudes.<\/jats:p>","DOI":"10.3390\/s90100175","type":"journal-article","created":{"date-parts":[[2009,1,8]],"date-time":"2009-01-08T06:00:18Z","timestamp":1231394418000},"page":"175-195","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Effects of Orbit and Pointing Geometry of a Spaceborne Formation for Monostatic-Bistatic Radargrammetry on Terrain Elevation Measurement Accuracy"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1236-0594","authenticated-orcid":false,"given":"Alfredo","family":"Renga","sequence":"first","affiliation":[{"name":"Department of Aerospace Engineering, University of Naples Federico II, 80 Piazzale Tecchio, 80125, Naples, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio","family":"Moccia","sequence":"additional","affiliation":[{"name":"Department of Aerospace Engineering, University of Naples Federico II, 80 Piazzale Tecchio, 80125, Naples, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2009,1,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"184","DOI":"10.1049\/ip-rsn:20045111","article-title":"Spaceborne bi- and Multistatic SAR: Potential and Challenges","volume":"3","author":"Krieger","year":"2006","journal-title":"Proc.
