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 기존 AESA 레이더 등과 달리 초광대역 방사파를
내보내는데 초광대역이라 전파교란 대항력이 뛰어나다네요.
실험용모델은 만들었고 실제 크기 목업을 만드는 중이랍니다.
KRET created an experimental sample of a photon radar for a sixth generation fighter
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"
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.
