More interesting news updates on photonic radars. https://itech.aorti.ru/upload/iblock/ac3/IT_23.pdf Google translated the pages.
"Then comes to mind
a person born in the Soviet Union when he hears the word
"Elik"? Possibly: “What has I reached?”
progress? To unprecedented miracles! Sank to the depths
and rose to heaven! ”In this children's film with a philosophical
the subtext of the android Electronics, or Elek, freed a person from routine duties, and Seryozha’s personality
Syroezhkina began to develop rapidly. About
the ELIK project can also change the development of modern business, science and defense
Institute of Radio Engineering
(RTI) named after academician Mints
and Mari State University.
"ELIK" stands for experimental
flight test complex. Scientists took up their development in 2013. To date, specialists
fully mastered the technology, created a workable layout and tested it
In action.
- The main value of the ELIK project is that
we have now created a completely new, unconventional
direction for RTI named after academician Mints, ”explains Anatoly Leukhin, Deputy General
Director of the Institute for Scientific Work. - Everyone knows that
we produce large ground stations, superradar. A competency
on the development of airborne radar systems
we did not have. Now it is -
we created inside the institute
such a technology. We can say that we will soon be ready to move to the production stage of the experimental
sample, and then serial
production.
In the framework of the ELIK project
developed hardware and software complex, one
part of which is installed on board an airplane or helicopter, the other is stationary
is on the ground.
The hardware part of the airborne radar consists
from several large building blocks. It is active
phased array X- and P-bands.
- In the X-band we reach a resolution of 30 cm
inclined range
and in azimuth. In the P-band
we achieve resolving
ability of 2.5 m in azimuth and range, - clarifies
Deputy General Director of the Institute.
Also in the side of the radar there are transmitting
modules, a device for transferring frequency to an intermediate frequency with subsequent
digitization of data, a device for recording holograms and the formation of radar images, block
recording navigation information and digital signal processing unit.
- We have right on board
it is possible to form a radio hologram and build radar
images, - says Anatoly Leukhin.
On the ground is set
complex simulation
modeling stand - high performance computing servers. It is used for computer
modeling, testing
all algorithms and the formation of model radar images.
- The software part of the onboard radar is
a large set of different procedures for the formation of radio holograms and radar
images, - reveals the details of Anatoly Leukhin. -
Given two polarizations,
excluding two polarizations,
with the construction of a pseudo-color or monochromatic radar image, with different functions
display dynamic alignment
on the screen, with a different set of autofocus algorithms, taking into account navigation information and without it
accounting, with adjustment of the horizontal component
speed and the vertical component of speed, etc.
That is, it is a very multifunctional program.
Software
works in real time and allows you to create a radar
image and even video data stream right on the screen
monitor.
This summer, onboard
radar project "ELIK"
passed tests at the Malino airport in the suburbs. He fully confirmed
scientists' calculations: equally
clearly sees objects in the fog,
in the rain, through dense foliage and tarpaulin, night and day.
As experts noted,
this is a great tool for
border control
and air reconnaissance.
- We counted on such results - they
were not news to us, -
says Anatoly Leukhin. -
But completely unexpected
in the radar pictures we saw large shields laid out by each
after another. There was nothing on earth, so first
did not even understand what it is.
It turned out that we got
underground vision results. These were stainless steel sheets. During World War II,
as the head of the airdrome later said, they served
runway.
Runway times
World War II was
covered in 30 centimeters
a layer of earth. Scientists continued the experiment and discovered cables of the same pore at a much greater depth.
However, airborne radar systems are inferior to optical instruments
remote sensing accuracy. Moreover, they
have a number of obvious advantages. The first is the absolute correlation between
radar images and humidity that
allows you to talk about the application in agriculture.
Secondly, in the optical range it is difficult to build
three-dimensional image, and in the radio range you can form a three-dimensional image with a very high
resolution
in height, and much easier than in optics. Therefore, where you need three-dimensional
scanning, a radar is preferable to optical. Another major benefit: sounding
land by airborne radar is much cheaper. It opens wide
opportunities for civilian use. For example, in archaeological
expeditions.
- If ELIK comes out
to the market and will be available,
then in archeology will happen
revolution! - Vladimir Poryvaev admires the opening opportunities,
military archaeologist and the first
officially recognized treasure hunter in Russia. - First of all, it will be possible to detect all the lost
military equipment of the Great Patriotic War and bury soldiers of all armies. And it’s not going to take decades to search,
but a few days. Next year is the 75th anniversary of the Victory,
and we could already put
point in that war saluting
to the last soldier.
Archaeologists work with
with small ground-based georadars, and in principle, devices
cope with their task.
For example, using a radar, a cave was discovered at the pyramid of the moon in the legendary ancient Mexican
the city of Teotihuacan. In Austria
under modern houses found archaeological
the remnants of the city of Karnunt are
the largest settlement of the ancient Romans in these places.
But the main problem of georadars is that you need to know where
to search. Endless steppes or
thick taiga with it
practically scan
impossible. A radar
the ELIK project gives an opportunity for carpet archaeological exploration: one flight -
and almost all the secrets of history
the world at a glance.
- The oldest cultural layer is located
at a depth of 30−35 m. But the ancient Roman, Mexican,
Russian settlements are located just 2 m below the surface of the earth, although they date back to 2-3 millenniums
BC. "ELIK" would allow in the literal sense of the word to look deep into
centuries, - so Vladimir Poryvaev imagines which
opportunities will open for
science and culture. - If we talk about point discoveries, then we can find a treasure
Kolchak (he is somewhere in Siberia), the treasure of Napoleon (in the vicinity of Vyazma). Guns, ancient weapons, decorations
Kremlin and the Cross of Ivan the Great - according to legend, trophies were taken out of Moscow burned
huge convoys.
The advantages of airborne radars are also obvious.
"ELIK" when controlling the sidebars
pipelines and inspection of oil pipelines underground and underwater at shallow depths. Airborne radar
can detect deposits
light oil, monitor the thickness of ice and monitor the ice situation in the North
sea way.
Now RTI named after Mints
is in negotiations with the holding
Russian Helicopters on the acquisition of on-board radars of the ELIK project. And although
the airborne radar market has not yet been formed,
according to Anatoly Leukhin,
their mass use
not far away. Firstly, because the best of them allow you to carry out all-inclusive
and round-the-clock observations, and secondly, all technologies are deeply developed, experimentally confirmed
and understandable their practical
significance.
It is only necessary to formulate it on the legislative
level. As soon as appropriate decisions are made, mass demand will not be long in coming. &

P-band The radar frequency band between 225 and 390 MHz. It is commonly used in remote sensing because of its good vegetation penetration.
Apparently pilots will become archaeologists.
