Type 1022 Radar

The Type 1022 Radar was an L-Band, long range, surveillance radar used by the Royal Navy. It is described as a STIR, Surveillance, and Target Identification Radar.[1]

Introduction

Following trials on HMS Grenville, Type 1022 was first installed in HMS Exeter in 1978, and HMS Invincible in 1979.[1] 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 older Type 965 and 992Q radar systems.[2] They were ineffective against the low flying aircraft using land for cover.[3][4] 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"[5] compared with the Type 965, "particularly in picking out targets against a background of clutter and interference produced by unwanted returns or enemy jamming."[5]

gollark: I think Ale32bit *also* did, though his was probably made after skynet.
gollark: `skynet.logs()` in the lua client, `{"type": "log"}` in the raw JSON protocol.
gollark: Also, you can see the logs too!
gollark: It's not bound to my server, it's just the default.
gollark: It should run perfectly fine on a raspberry pi, if you wanted to do that, so it's not particularly *hard* to keep it going.
