러시아, 광자레이더 기술실증품 테스트 완료

 

 개발사가 시제 실증품 테스트 완료 했다 했고

신기술로 레이더 크기 크게 줄여 전투기에

탑재할 수 있게 됐다네요.

 

 2017년 기사는 공동개발사 KRET 부사장 인터뷰인데 

광자레이더는 광결정에서 나오는 레이저를 극초단파로 

변환시켜 레이더 신호를 얻으며 레이더파로 변환시키는 

에너지 중 60~70%가 열로 손실 되는 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.

 

  그리고, 광자레이더가 목표물을 스크린에 점이 아닌 구체적

 이미지로 표시 한답니다.

 

 

 

 Developement of Roseletronics will allow more accuracy

to determine the opponent's goals

 The Vega Concern of the Ruselectronics holding has

completed tests of a prototype demonstrator of an active

phased antenna array based on radio photonics (ROFAR).  

 

 The new technology will significantly reduce the size of

onboard radars and allow them to be integrated into the

hull skin of aviation and marine equipment, which will

increase the radar's field of view. 

 

 The active antenna array with a high-speed scanning

system created within the framework of the project is

built on the basis of distributed radio-photonic transceiver

modules, in which the original domestic component base is used. 

 

 It is assumed that the resolution of the new radar will be

several times higher than the existing systems and will make

it possible to more accurately determine enemy targets with

an increased scanning range.

 

 

 

 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"

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.
