러시아, 전투기용 광자레이더 기술실증품 테스트 완료
개발사가 기술실증품 테스트 완료 했다고 발표한 거고
양산품 제작으로 꾸준히 나아가고 있는 걸로 보입니다.
아래 2017년 기사는 공동개발사 KRET 부사장 인터뷰인데
광자레이더는 광결정에서 나오는 레이저를 극초단파로
변환시켜 레이더 신호를 얻는답니다.
또, 레이더파로 변환시키는 에너지 중 60~70%가 열로
손실 되는 기존 레이더와 달리 에너지 보존율이 60~70%라
하구요.
그에 따라 탐지 범위가 그만큼 늘어나게 되는 거죠.
또, 광자레이더는 AESA 레이더 등과 달리 초광대역 방사파를
내보내서 전파교란 대항력이 뛰어나다네요.
Russia completed tests of a photonic radar for detecting stealth targets
2020.08.29
Tests of the prototype active phased array antenna based on
radio photonics (ROFAR) have come to an end. Vyacheslav Mikheev,
General Director of Vega Concern, spoke about this.
According to him, the technology will make it possible to reduce
the size of airborne radar stations of aircraft and ships, as well as
increase the accuracy and detection range of stealth targets.
An active antenna array with a high-speed scanning system is
built on the basis of distributed radio-photonic transceiver modules.
They use the original domestic component base.

KRET created an experimental sample of a photon radar for a sixth generation fighter
2017.07.27
The first deputy director general Mikheev noted that "now a full-scale mock-up of this
radio-optical photonic antenna array is being created within the framework of scientific
research that will allow us to fulfill the characteristics of a serial model."
KRET also develops technologies of specific elements of the new radar - its emitter,
photonic crystal, receiver path, resonators.
As explained by Mikheev, in a conventional radar , the radiation is generated by
electrovacuum or semiconductor devices, their efficiency is relatively low - 30-40%.
The remaining 60-70% of the energy is converted into heat.
"In the new radar, the radar signal is obtained by converting the energy of a coherent
laser into microwave radiation by a photonic crystal. Such a transmitter will have an
efficiency of at least 60-70%, that is, most of the laser energy will be converted to radar"
he said.
On the photonic transmitter it will also be possible to obtain ultra-wideband radiation,
which is physically impossible on a conventional radar.
The new radar due to its ultra-wideband and huge dynamic range of the receiver will
have great opportunities to protect against interference.

RTI tested a prototype model of a radiophotonic radar of a new generation
2019.06.27
The general director of the RTI group, Maxim Kuzyuk, said this in an interview with
TASS on Thursday in the framework of the Army-2019 forum.
Due to the use of photon technologies on the radar screen, the targets will not be
displayed in the form of points, but images. That is, the operator will see the real goal
- an airplane, a rocket, a drone or a meteorite.
