Declared for a fighter of the 6th generation, radio-photon radar
will be created in Russia in a couple of years
2018.07.09
The press service of the RTI was noted that the company in 2018 is
completing the research work on creating a model of a radio-photon
radar (X-band).
According to its results, "the fundamental scheme for constructing a
radio-photon locator will be determined," added to the RTI that "in a
few years time it will be possible to produce samples of ultralight and
small-scale radar for unmanned aerial vehicles."
The radar signal in a new type of station is obtained by converting the
laser energy in a photonic crystal. The RTI was informed that the
production of lasers for such radars is already beginning.

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.
