개발사 KRET 부사장에 따르면 광자레이더는 광결정에서 나오는
레이저를 극초단파로 변환시켜 레이더 신호를 얻으며 레이더파로
변환시키는 에너지 중 60~70%가 열로 손실되는 기존 레이더와
달리 에너지 보존율이 60~70%라고 합니다.
그에 따라 탐지 범위가 그만큼 늘어나게 되는 거죠.
또, 광자레이더는 AESA 레이더 등과 달리 초광대역 방사파를
내보내서 전파교란 대항력이 뛰어나다네요.
실험용모델은 만들었고 실제 크기 목업을 만드는 중이랍니다.
예전에 PAK-FA에도 탑재할 거란 얘기도 있었습니다.
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.
