Titolo: | CLUSIM: A Synthetic Aperture Radar Clutter Simulator for Planetary Exploration | Autori: | Ilyushin, Ya. A. OROSEI, ROBERTO Witasse, O. Sánchez-Cano, B. |
Data pubblicazione: | 2017 | Rivista: | RADIO SCIENCE | Numero: | 52 | Fascicolo: | 9 | Da pagina:: | 1200 | Abstract: | In this paper we present the CLUtter SIMulator (CLUSIM), a special program simulating radar side echoes from rough planetary surfaces using realistic topography data sets. A numerical model of realistic topography of the Martian surface, based on Mars Orbiter Laser Altimeter data, is developed. A specially developed computer routine for evaluation of wideband radar echoes reflected from rough surfaces, capable of aperture synthesis simulation, is described. A synthetic radargram for a portion of Mars Express (MEX) orbit 9466 is computed and validated against experimental data obtained by the MARSIS radar instrument. Finally, a previously developed ionospheric phase correction procedure is numerically tested with new simulated echo signals. Impact of the surface clutter on the ionospheric correction procedure is investigated with a direct numerical comparison to a known benchmark result, which shows robustness of the correction algorithm with respect to the surface clutter. | URI: | http://hdl.handle.net/20.500.12386/27135 | URL: | https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2017RS006265 | ISSN: | 0048-6604 | DOI: | 10.1002/2017RS006265 | Bibcode ADS: | 2017RaSc...52.1200I | Fulltext: | open |
