At the moment, space awareness solutions are among the most calling research topic. In fact, it is vital to persistently observe and characterize resident space objects. Instrumental highlights for their characterization are doubtlessly their size and rotational period. The Inverse Radon Transform (IRT) has been demonstrated to be an effective method for this task. The analysis presented in this paper has the aim to compare various approaches relying on IRT for the estimation of the object\u2019s rotation period. Specifically, the comparison is made on the basis of simulated and experimental data.<\/jats:p>","DOI":"10.3390\/s21041298","type":"journal-article","created":{"date-parts":[[2021,2,12]],"date-time":"2021-02-12T18:45:00Z","timestamp":1613155500000},"page":"1298","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Experimental Comparison of Radon Domain Approaches for Resident Space Object\u2019s Parameter Estimation"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9894-0839","authenticated-orcid":false,"given":"Selenia","family":"Ghio","sequence":"first","affiliation":[{"name":"National Laboratory of Radar and Surveillance Systems (RaSS), Consorzio Nazionale Interuniversitario per le Telecomunicazioni (CNIT), 56124 Pisa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marco","family":"Martorella","sequence":"additional","affiliation":[{"name":"National Laboratory of Radar and Surveillance Systems (RaSS), Consorzio Nazionale Interuniversitario per le Telecomunicazioni (CNIT), 56124 Pisa, Italy"},{"name":"Department of Information Engineering, University of Pisa, 56122 Pisa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniele","family":"Staglian\u00f2","sequence":"additional","affiliation":[{"name":"ECHOES srl, 56023 Cascina, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dario","family":"Petri","sequence":"additional","affiliation":[{"name":"ECHOES srl, 56023 Cascina, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefano","family":"Lischi","sequence":"additional","affiliation":[{"name":"ECHOES srl, 56023 Cascina, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Riccardo","family":"Massini","sequence":"additional","affiliation":[{"name":"ECHOES srl, 56023 Cascina, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,11]]},"reference":[{"key":"ref_1","unstructured":"Portree, D.S., and Loftus, J.P.
