Japan’s Radar Network
by James Simpson http://jsw.newpacificinstitute.org/?p=4011
Extent of Radar Network
The computerised network, known as JADGE (Japan Aerospace Defense Ground Environment), is operated and maintained by the ASDF. It was originally developed in the early 1960s from the handover of USAF stations, and some of the equipment dates back to these origins (e.g. AN/FPS-20), and became operational in 1989. Generally located on coastal mountain tops, the radar systems afford the ASDF full coverage of the Japanese islands.
The above map was recreated and adapted from a book by Toshiyuki Shikata, retired GSDF Lt. General, Professor at Teikyo University and security advisor to the Governor of Tokyo, Shintaro Ishihara – a clear authority on Japanese military issues. It shows the location of ASDF sub-bases with radar installations, and their overlapping coverage at 50, 75, 130 and 200 nautical miles (note the map in the book, and the one above, is simply an approximation). What is clear is that at 200NM, Japan is fully covered by its air defense radars, although the full range of the newer installations, and limitations of the older ones are not included (they are presumably kept secret for national security).
The early-warning installations provided by JADGE also support electronic and electro-magnetic measurement intelligence (ELINT/ESM) collection stations – near Wakkanai, Nemuro, Okushiri, Seburijima, Fukuejima, Misawa and Miyakojima. There are reports of communications intelligence (COMINT) collection stations near Takaoyama, Fukuejima and Miyakojima.
Composition of Radar Network
The 28 integrated facilities around Japan that comprise JADGE are coordinated via the US-developed Link 16 Joint Tactical Information Distribution System (JTIDS)/Multifunctional Information Distribution System (MIDS) at ASDF Air Defense Command, currently being transferred to Yokota AFB from Fuchu Air Station.
The ASDF operates seven J/FPS-2 static three-dimensional radars, first installed in 1979 with a range of 200 km (approx. 100 nautical miles).
A further seven facilities operate the recently upgraded J/FPS-3A, a three-dimensional phased array radar with a search range of around 370 km (approx. 200 nautical miles) and height-finding at 150 km (approx. 80 nautical miles).
The most modern additions to the network are the six J/FPS-4 sites and the five J/FPS-5 sites, while older AN/FPS-20 and AN/FPS-6 radars operate at four sites (one per Air Defense Force).

Spoiler for J FPS5 Radar:

J/FPS-5 Fixed 3D Radar
The FPS-5 is Japan’s most advanced fixed radar installation in its ballistic missile defense system. Its distinctive tortoise shell-like dome covers have earned it the nickname ‘Gamera radar’ after Godzilla’s turtle-derived rival. Mitsubishi Electric produce the 34-metres high structures containing three antennae of between 12- and 18-metre diameter.
The FPS-5 prototype was constructed at the Ministry of Defense research facility in Iioka, Chiba Prefecture in 2004. At the end of 2008, the JASDF Shimo-Koshikijima Sub Base in Kagoshima Prefecture brought the first unit up and running, and the radars mistakenly detected a North Korean missile launch just a day before the Kwangmyongsong-2 satellite launch in April 2009.
The second came online in 2009 at JASDF Sado Sub Base in Niigata Prefecture, followed by the third in 2010 at JASDF Ominato Sub Base in Aomori Prefecture. Next year, the fourth FPS-5 should be up and running in the ASDF Yozodake Sub Base on Okinawa Island – it was originally scheduled to be completed in 2011.

Postingan dari thread AA JSDF, tapi dibuat thread tersendiri deh biar ramai. Lama ndak ada thread Radar/ Air Defense...
Hal menarik adalah gelar radar yang tersebar di jalur pegunungan dan ada overlapping coverage area , juga diperkuat dengan electronic and electro-magnetic measurement intelligence & communications intelligence
Semuanya terintegrasi
. Tidak lupa ditambah patroli maritim P-3C Orion dan gelar Aegis Ship sebagai lapis pertahanan maritim. Minimnya SAM tapi melimpahnya air superiority fighter di JSDF menjadi ciri khas pertahanan udara yang berkiblat ke NATO... Bandingkan pertahanan udara ala Blok Timur yang lebih terdengar gelar SAM-nya sebagai unsur 'penindak' ...CMIIW.
Menurutku ini bisa jadi model pertahanan udara nasional Indonesia lho. Tapi seharusnya kita harus lebih kompleks karena:
1. Pulau kita jauh lebih banyak.
2. Pulau utama kita dipisahkan oleh laut, bukan sekedar selat seperti Jepang.
3. Lalu lintas pelayaran dan penerbangan internasional yang melewati teritorial Indonesia jauh lebih ramai.
Lantas, di jaman modern begini integrasi maritime surveillance & air defence sudah menjadi kepantasan. Sepertinya Kohanudnas perlu memasukan elemen dari AL. Tapi sayang kita belum punya kapal-kapal dengan air surveillance yang mumpuni dan pesawat patroli maritim juga masih minim.
