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]



Technical Specifications


Beam Width: 2.3°

Range: 225 nm (~259 miles)

Rotations speed: 6-8 RPM

Band/Wavelength: 1-2 GHz (Civil L-Band, Military D-Band)

Understanding the information contained in the Deep Space Network XML data?

up vote 1 down vote favorite NASA's Deep Space Network activity can be viewed conveniently at https://eyes.nasa.gov/dsn/dsn.html but if you would like data in a more raw XML form, it can be accessed as described in this answer Below is a small Python script that reads the XML into a list of dictionaries, and saves it to disk as a JSON. The dictionaries are organized at the higher level by dish, then by spacecraft per dish. Question: What are the most-likely meanings of all the data field contained in the Deep Space Network XML data?
