This is expected to aid radar engineers and researchers in systems design, testing, and training. The program supports the short- and long-range simulation of various radar scenarios using complex target and signal models with a high degree of realism. This was achieved through raytraced radio propagation and geometry modelling, simulating realistic multipath signal interactions with mesh-based objects as opposed to the more traditional point-model approach. The designed algorithm has also been implemented as an open-source ray-tracing module and was verified against an established radar software package.<\/jats:p>","DOI":"10.12720\/jcm.17.9.761-768","type":"journal-article","created":{"date-parts":[[2022,10,8]],"date-time":"2022-10-08T21:56:58Z","timestamp":1665266218000},"page":"761-768","source":"Crossref","is-referenced-by-count":7,"title":["The Design and Implementation of a Ray-tracing Algorithm for Signal-level Pulsed Radar Simulation Using the NVIDIA\u00ae OptiXTM Engine"],"prefix":"10.12720","author":[{"name":"University of Cape Town, Cape Town 7701, South Africa","sequence":"first","affiliation":[]},{"given":"Mogamat Yaaseen","family":"Martin","sequence":"first","affiliation":[]},{"given":"Simon L.","family":"Winberg","sequence":"additional","affiliation":[]},{"given":"Mohammed Yunus Abdul","family":"Gaffar","sequence":"additional","affiliation":[]},{"given":"David","family":"Macleod","sequence":"additional","affiliation":[]}],"member":"4977","published-online":{"date-parts":[[2022]]},"container-title":["Journal of Communications"],"original-title":[],"link":[{"URL":"http:\/\/www.jocm.us\/uploadfile\/2022\/0826\/20220826050938945.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,10,8]],"date-time":"2022-10-08T21:57:11Z","timestamp":1665266231000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.jocm.us\/show-276-1818-1.html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022]]},"references-count":0,"URL":"https:\/\/doi.org\/10.12720\/jcm.17.9.761-768","relation":{},"ISSN":["2374-4367"],"issn-type":[{"value":"2374-4367","type":"print"}],"subject":[],"published":{"date-parts":[[2022]]}}}
