Radar, fielded in war as a means of detecting approaching aircraft and ships by radio reflection well before they came into visual range, entered operational service in Britain as the Chain Home network, built up along the English coast in stages from 1937 to 1939. Chain Home gave the Royal Air Force the advance warning it needed to intercept incoming German raids rather than keep costly standing patrols aloft, an advantage credited as a significant factor in the Royal Air Force's victory in the Battle of Britain in 1940. Wartime demand for smaller, more capable sets also drove the development of airborne radar for night fighters and maritime patrol aircraft over the rest of the war. This entry covers radar as fielded and used in war; the invention and technical development of radar itself is Technology's own subject, cross-linked rather than duplicated here.

Wikipedia- During World War II section
Lead section, first paragraph
Radar is a system that uses radio waves to determine the distance (ranging), direction (azimuth and elevation angles), and radial velocity of objects relative to the site.
- Weapon class classified from the entity's own sourced description text.
- Correction: a detection/electronic system, not an aircraft.
Used In: World War II, Article text: sections
This device was developed secretly for military use by several countries in the period before and during World War II.
Operated By: Royal Air Force, Article body
This system provided the vital advance information that helped the Royal Air Force win the Battle of Britain; without it, significant numbers of fighter aircraft, which Great Britain did not have available, would always have needed to be in the air to respond quickly.
In Group: Radar, Navigation and Electronic Warfare Systems, Lead sentence
Radar is a system that uses radio waves to determine the distance (ranging), direction (azimuth and elevation angles), and radial velocity of objects relative to the site.
