Quote:Air Force Aims for Stealth-Detection Radar by 2020

Military authorities want to procure a radar capable of detecting stealth aircraft by the mid-2020s as China and Japan boost their military arsenal.

An Air Force officer on Wednesday said, "The Air Force first called for stealth-detection radar in July 2011, and the Joint Chiefs of Staff decided in November last year to build such a detection system in the long term."

"The Agency for Defense Development and other institutes are developing a stealth-detection radar. Once we know how good the domestic technology is, we'll decide whether to develop the radar independently or buy it from abroad," another military officer said.

The military is developing several models including low-frequency radar.

"Experts predict that stealth-detection radar will be developed in four to five years," Defense Minister Kim Kwan-jin told the National Assembly's Defense Committee last month.

A military source said, "Nobody knows how much it'll cost to develop a stealth-detection radar because none exists so far."

China, Japan and Russia are all developing or planning to procure stealth fighter jets between 2016 and early 2020.

China is developing two kinds of stealth fighters.

In December 2011, Japan picked the F-35 stealth fighter jet as its main next-generation fighter model and decided to procure 42 of them starting in 2016.

Russia is developing a stealth fighter with the goal of deploying it warfare-ready in 2016.

Quote:Korea Develops Core Stealth Technology

The Korean military has reportedly succeeded in developing the core technology for stealth fighter planes. Stealth technology is used to disguise aircraft or vessels from detection by radar, infrared or sound detectors. Stealth is considered a key field in future warfare, and world military powers such as the U.S., China, Japan and Russia have been focusing efforts on developing it.

A Korean military source on Monday said that the Agency for Defense Development (ADD) and other local defense research institutes began developing stealth fighter technology and application systems in 1999. They developed radar absorbent material by the end of 2002, and are now aiming to finish developing all core technologies for functional stealth by mid-2010.

Military authorities plan to finish tests of some of the radar absorbent material for application to weapons systems, including fighter jets, by the end of this year.

According to the military source, top-secret ground tests were done on F-4 fighter jets and miniature jet fighter models equipped with the radar absorbent material until 2007. The tests were satisfactory. It has not been revealed if the domestically developed material is ordinary paint or come in some other form. F-117 fighter bombers, an early U.S. stealth aircraft, used thick stealth painting. The newer F-22 stealth fighters reportedly use a much thinner coating.

The ADD and other local defense research institutes have also developed stealth configuration technology to design fighter jets and vessels that can effectively avoid radar detection.

The military source explained that Korea is developing stealth technology as "U.S. F-22s are already deployed for war-related duties, and neighboring countries such as China, Russia and Japan are striving to secure the stealth technology and apply it to their weapons systems with the aim of securing command of the air in Northeast Asia."

So.....sejauh mana kemajuan buat KFX/IFX emoticon-Malu (S). Program di pending tapi penelitian jalan terus gitu??
lihat dulu sikonnyaemoticon-Traveller
Yang menarik, Korea Selatan tidak hanya menganggap China sebagai potensial adversary tapi Jepang juga emoticon-Big Grin
hayooo daripada KFX yg masih maju mundur mending TOT yg ini emoticon-Embarrassment

iya juga seh secara singapor ma ozy kedepan juga mau dapet F 35 baiknya bikin radarnya dulu biar bisa ngendus. sambil menunggu KFX jadi dan kayaknya juga radar ini juga mau dipasang di KFX

bakar menyan moga2 suhu radar formil Stealthflengker nongol bisa kasih pencerahan ??
jangan lupa kalo masalah stealth, cat trimaran kalo g salah anti radar loh,

semua pesawat tempur, angkut, angkut militer, helikopter dll, udah di cat belum ya pake cat anti radar klewang?

Selama senjata masih taroh diluar ya jangan ngimpi Stealth emoticon-Embarrassment

radar apa ?

Low Frequency Radar untuk mendeteksi pesawat stealth itu panjang gelombangnya 2 meter lho (VHF). Nggak ada itu pespur punya ruangan untuk radar semacam itu.

Bisanya ya di darat.

makanya gw jadi males begitu tau batal pake internal bay....
ngapain cape2 riset shape kalo ntar rcsnya melonjak gila ama gendolan ? emoticon-Nohope
mong omong anggarannya KFX bakal bengkak gak tuh ? dulu PAK-FA juga dikasih modal 10 milyar dollar (tapi kyknya nembus jauh ) emoticon-Thinking

anti stealth L-band yang desainnya buat di bahu pak-fa pake teknik apaan tuh ?

Karena dia L-Band yang panjang gelombangnya masih 20-30 Cm. Jadi masih memungkinkan untuk menggunakan antenna yang kecil buat ditanam di leading edge sayap. Dan menghasilkan pancaran dengan ukuran yang sesuai untuk aplikasi radar.

Lha kalau VHF.. 2 m, gede itu antennanya dan antennya hmm nggak bisa itu makai microstrip.. atau slot, ya harus YAGI atau seperti Vostok yang make Kharchenko square.. Mau ditaroh dimana.

nambahin contohnya om :
Spoiler for nebo:


1L119 Nebo SVU, vhf radar aesa 14*6 elemen,
Detection range for aircraft and ballistic targets with RCS of 1 m2, km:
at 0.5 km altitude, 65 km
at 10 km altitude, 270 km
at 20 km altitude, 380 km

Measurement Accuracy:
range, 200 m
azimuth, 30 arcmin
elevation angle, 1.5 arcmin (within 3 to 45 deg elevation angle range)


antena segede gini ya ga bakal muat di pesawat..


radarnya mungkin gede bgt ini krn yg dideteksi objek dgn RCS sebesar bola. tapi kbutuhan listriknya gmana yah? apa burung terbang juga ikut terdeteksi ga yah?

Ya kalau radar darat make generator gan.

mengenai masalah burung..bisa saja terdeteksi, tapi difilter supaya tidak menganggu pencarian target.

tapi bisa brintegrasi dgn SAM jg kan? Indonesia harus punya radar bgini nih drpd nunggu IFX biar tetangga kita mikir2 ngintip di teritorial kita.

listrik : Power consumption, 30 kW, ya masih genset sedang..

soal ukuran ya karena pake vhf band frek 150 Mhz, panjang gelombang 2m. ukuran per elemen antena 3/8 lamda = 3/8* 2 = 0.75 m. jarak vertikal antar elemen kalau dilihat dari foto kira2 1/2 lamda = 1m, ada 6 elemen, ukuran tinggi total dah 5 m, jarak horizontal 1 lamda = 2m, ada 14 array jadi lebar 26 m, ukuran antena radar 5m*26m, kalau yang model nebo svu ini belum ada data resmi bisa di konek ke s400/s300. yang sudah bisa yang L-band radar NNIIRT Protivnik GE. maennya di frekuensi 1.3 Ghz (panjang gelombang 23 cm). tapi elemen harus lebih banyak dan Power rating lebih besar berakibat butuh listrik lebih besar, radar ini butuh listrik 100 kw.

spek teknisnya ane masih blm bisa memahami. apakah ukuran radarnya 26m2?
di destroyer 052C PLAN yagi juga ya mas
