Type 1022 Radar

The Type 1022 Radar is an L-Band, long range, surveillance radar used by the Royal Navy. It is described as a STIR, Surveillance, and Target Identification Radar.

Introduction
Following trials on Grenville, type 1022 was first installed in HMS Exeter in 1978, and HMS Invincible in 1979. Following successful implementation in newly built warships it was then adopted in further units during refit; these include: Early (Sheffield Class) type 42 destroyer, Type 82 destroyer

Performance
During the Falklands War many ships were fitted with the obsolete type 965 and 992Q radar systems. They were ineffective against the low flying aircraft using land for cover. The 1022 upgrade allowed better target acquisition on low flying, ground hugging targets.
