The '''SCR-658 radar''' is a [[radio direction finding]] set <ref>{{cite book|title=The Roswell report : fact versus fiction in the New Mexico desert.|url=https://books.google.com/books?id=qrsIzxnsAjgC&pg=RA5-PA52|year=1995|publisher=DIANE Publishing|isbn=978-1-4289-9492-8|pages=5–}}</ref> introduced by the [[U. S. Army]] in 1944,<ref>{{cite book|title=Bulletin of the American Meteorological Society|url=https://books.google.com/books?id=JhYaAQAAMAAJ|year=1958|publisher=[[American Meteorological Society]]|pages=402–}}</ref> was developed in conjunction with the [[SCR-268 radar]]. It was preceded by the SCR-258. Its primary purpose was to track weather balloons. Prior to this it was only possible to track weather balloons with a [[theodolite]], causing difficulty with visual tracking in poor [[weather]] conditions. The set is small enough to be portable and carried in a [[Ben Hur trailer]].

==Surviving examples==
There is one known survivor at the Air Force museum in [[Dayton Ohio]].<ref>{{cite web |url=http://www.nationalmuseum.af.mil/photos/index.asp?galleryID=4881 |title=National Museum of the USAF - Photos |website=www.nationalmuseum.af.mil |url-status=dead |archive-url=https://web.archive.org/web/20121011025702/http://www.nationalmuseum.af.mil/photos/index.asp?galleryID=4881 |archive-date=2012-10-11}} </ref>
