الموضوع عامل حرقان شديد للبعض ، كنت انتظر ردود علمية و تقنية تدعم او تفند لكن لا شيء غير التهريج
رادار الجيل الاول N036 لـ SU-57 و اشكالية البصمة الالكترونية

تضيع وقتك مع واحد مصدره Quora و يقولك ان N036 جيل اول و لم يذكر حتى شيء على انه GaAs/LLTC 3D و في 2025 راح يتم تحديث Su-57 باستبدال جميع الكترونيات و حتى الرادار

لديك مصدر ان N036 ليس بجيل اول رغم استخدامه لتقنية Patch/Slotted و ضعفه في خصائص LPI ؟
على العموم ننتظر 2025 لنرى كيف سيكون التحديث

لمذا تكذب هناك عدة مشاريع مشتركة مع روسيا لصناعة رادارات الفوتون مثلما تمت صناعة صواريخ برق و صاعقSU-57DZ ستحصل على رادار فوتوني

نعم راح يتم استبدال جميع الكترونيات وراح يكون رادار من GaAs الى GaN

An important line of activity for KRET is the development of
ultrabroadband antenna systems using the AESA active phased array
radar. In the AESA, every element or group of elements has its own
miniature microwave transmitter, working in the frequency band
from 1 to 18 GHz.
Powerful solid-state amplifiers, made of gallium-arsenide and
gallium-nitride technologies, are used as AESA’s active elements in
modern EW solution. Thanks to them, the equipment’s weight can be
reduced by 1.5–2 times, raising reliability and efficiency by 2–3 times.
Since you have stated broadband sucks and that narrow band is better at a gain. Can transceivers like this limit their broad frequency scope to a narrow frequency? Why I also hinted the fga-35 (3d) is that its weight reduction as a radar from a previous AESA radar got drastically reduced by 1.5-2 times similar to the weight of the EW systems that got reduced by 1.5-2 times smaller being based with the same LTCC MMICs.

Current radar receivers cover like 1-18ghz give or take, GaN AESA based modules for EW systems have been told to cover UHF/VHF according to some Russian and US sources. So the next issue is photonic radars going up to 100ghz. Mikheeyev said the same multi-band radar technology can be found on the SU-57 when talking about ROFAR. So looking at the 1st image my focus is on the 17-100ghz tracking frequencies its more horrible than X-band but can be better than IRST around 300gh?.

ROFAR offers:
less internal noise. Higher frequencies than X-band suffer more internal noise but according to them these radars lower the noise inside the radar systems.
Claims of immunity to EW. This seems to be true because if you are shooting for example 20ghz at another current 5th gen whose receivers can go up to 18ghz its not like they can suppress those waves.
