South Korea Signals AESA Progression
Citat:South Korea’s Defense Acquisition Program Administration (DAPA) has signalled progression in its programme to develop an active electronically scanned array (AESA) radar system in collaboration with local industry.

DAPA said in a statement on 31 May that its radar programme – intended to support the Korean Fighter Experimental (KFX) aircraft – has completed a two-year preliminary design phase and will now move to the critical design stage before a design review in May 2019.

Following the design review, DAPA hopes to produce a pilot prototype in 2020, which will be installed on early prototypes of the KFX from 2022. After several years of trials, DAPA aims to start initial production of both the aircraft and its AESA radar from the mid-2020s.

Leonardo launches new E-scan radar for fighter jets ‘Grifo-E' at Farnborough Air Show
Citat:The Grifo-E draws on Leonardo’s established expertise in E-scan radar to offer a system with a variety of advanced new modes that comes in a flexible, cost-effective package

• The Grifo-E is the evolution of the Grifo (M-scan) radar, which has been widely adopted with 450 units installed on seven types of aircraft for six air forces

• Leonardo’s 2018-2022 Industrial Plan sees the success of products like the Grifo allowing for re-investment in targeted technology areas for long-term sustainable growth

^ Sve u redu, samo što antena na fotografji nije AESA. To je neki stariji model Grifo radara. Traljavi su talijani, sami sebi prave antireklamu.

Northropov Gan Aesa-Vanguard


Citat:
The core of the Vanguard radar is a modular radar assembly measuring 1 sq. ft. It can operate as a standalone antenna for surveillance, electronic-support measures and communications, or combine with adjoining arrays to form a single radar system.

Citat:Compared to the S-band SPY-6, Northrop offers the first version of Vanguard with dual-band capability, Pearson says. The Vanguard can track distant targets through weather in X-band, or switch to Ku-band to acquire a higher-resolution image at shorter ranges.

Citat:The Vanguard can be offered as a single radar assembly that can be carried by a platform as small as a medium-size unmanned air vehicle. It also can combine more than a dozen radar assemblies into a radar with the length of the E-8C’s APY-7 radar, except such a Vanguard system could simultaneously perform several functions—including SAR/GMTI, ESM and communications.

Izvinjavam se, ovo je tema za AESA, ali mislim da ovi linkovi dole za principe rada PESA radara, sa naglaskom na N007 Zaslon za MiG-31 i uz neke osvrte i na N035 Irbis za SU-35, zaslužuju da na nekoj temi ostanu vidljivi i ne zatrpani.....

Kinezi izlazu na Zhuhai airshow-2018
Za sada samo sture informacije
Three-aerial AESA fire control radar to appear at Zhuhai airshow
Citat:A new press release by China Electronics Technology Group Corporation No.14th Research Institute on Nov. 2 says it’ll be showing a new three-aerial AESA fire control radar at Zhuhai airshow.Not much was disclosed in the single paragraph except that the radar will be able to “see behind.”. This is probably similar to the Russian N036 Byelka radar that is mounted on the Su-57.
