The '''Type 1022''' was an [L-Band](/source/L-Band), long range, surveillance [radar](/source/radar) used by the [Royal Navy](/source/Royal_Navy). It is described as a STIR, Surveillance, and Target Identification Radar.<ref name="FriedmanNorman">{{cite book|last=Friedman|first=Norman|title=The Naval Institute Guide to World Naval Weapon Systems|year=2006|publisher=Naval Institute Press|isbn=1557502625|pages=299–300}}</ref>

== Introduction ==
Following trials on [HMS ''Grenville''](/source/HMS_Grenville_(R97)), Type 1022 was first installed in {{HMS|Exeter|D89|6}} in 1978, and {{HMS|Invincible|R05|6}} in 1979.<ref name="FriedmanNorman" /> Following successful implementation in newly built warships it was then adopted in further units during refit; these include: Early (''Sheffield Class'') [Type 42 destroyer](/source/Type_42_destroyer), [Type 82 destroyer](/source/Type_82_destroyer).

== Performance ==
During the [Falklands War](/source/Falklands_War) many ships were fitted with the older [Type 965](/source/Type_965_radar) and [992Q](/source/Type_992_radar) radar systems.<ref>{{cite book|last=Moore|first=John|title= Jane's Fighting Ships 1981-1982|year=1981|publisher=Jane's Publishing Company Ltd.|location=London|isbn=0 7106-0728-8}}</ref> They were ineffective against the low flying aircraft using land for cover.<ref>{{cite book|last=Hart-Dyke|first=David|title= Four Weeks in May: The Loss of HMS Coventry|year=2007|publisher=Atlantic Books|location=London|isbn=978-1-84354-590-3}}</ref><ref>{{cite book|last=Woodward|first=John F.|title= One Hundred Days: The Memoirs of the Falklands Battle Group Commander|year=2012|publisher=Harper Collins|location=Hammersmith, London|isbn=9-780007-436408}}</ref> The 1022 upgrade allowed better target acquisition on low flying, ground hugging targets.  The Type 1022 radar is described as having a "much improved performance"<ref name=Marriott118/> compared with the Type 965, "particularly in picking out targets against a background of clutter and interference produced by unwanted returns or enemy jamming."<ref name=Marriott118>{{citation|page =118|title=Royal Navy Frigates Since 1945|first1=Leo|last1=Marriott|edition=2|publisher=Ian Allan Ltd|date=1990|isbn=0-7110-1915-0}}</ref>
