Miguel Aresta said:Does anyone have a photo on the "mysterious" Soyuz radar ? The one from the Soyuz programme headed by NPO Istok ..
It appears so.
80 years of the Soviet Union was the best radar, but not the rank and file charges later NIIP meal or two, but Istok СИНТЕЗ series of radar, then When the radar is successfully developed, it can be said that the above two streets are smashed!
The radar sample and the photos of the experiment at that time, the general situation of the aircraft modified with Figure-128 is that the Soviet airborne radar development was monopolized by Fazoton and NIIP, similar to the current 14 and the thunder and lightning yard pattern, NPO Istok provided them with microwave devices, but in the mid-1970s, with the support of Shaojin, the father of the Soviet microelectronics industry, Istok cooperated with the Pennant Design Bureau, which developed the missile seeker at that time, to ?Союз – Синтез Name the development of a new type of airborne radar (Shao Jin was very dissatisfied with the Soviet Union 's rigid system at the time, leading to the backwardness of Soviet electronic technology, encouraging innovation, so they dared to engage in this plan ). The radar project started in the mid-1970s, which is the "Myech" airborne radar project in the Su-27 project, because the lag of that project caused Simonov to overthrow the early design and restarted. Decided to encourage innovation and start a new generation of airborne radar. The most classic product they developed successfully was СИНТЕЗ-10, probably in the mid-1970s. In the process of developing this airborne radar, Istok used its own technological advantages to create “multi-beam” transparency in the world. Technology such as traveling wave tube, ultra-low noise small electrostatic discharger and three-dimensional large-angle antenna hydraulic system. In the development of airborne radar, the first result in the Soviet Union was obtained: based on Soviet domestic components. The airborne radar with programmable digital signal processing function was developed. When the airborne radar was tested for flying, the trajectory processing method was used in the "target search" state to verify the calculated value of the target discovery distance. The target area of the square meter is more than 200 kilometers away; the ground is real-time imaged with a synthetic aperture antenna with a resolution of 7 meters.
This radar code is "synthesis", which means the experimental synthetic aperture technology. The radar is designed and tested successfully in the 80s, but the radar itself is advanced in technology. Unfortunately, the radar is too advanced and exceeds the design requirements of the Soviet Air Force.(!? Really, the Soviet Air Force feels too advanced and a little uncomfortable), and more importantly, it touched the breasts of the two old big companies, and it’s not fun (like today’s domestic, halfway to kill a bite, Changhong) Also said that the airborne radar, 14 and the Thunder and Light Institute is not good.) Under the system at that time, it was put on the shelf and was blocked. Later, Istok was no longer involved in airborne radar. Later, Istok went to China to sell products and technology, which revealed this inside story, but at that time, the domestic cooperation with Fazoton did not happen.
According to the decision of the government military committee, Istok developed the development of airborne radar. The most sophisticated electronic products were developed and produced in the electronics industry's enterprises – airborne radar for the new generation of fighters.
The "Синтез-10" airborne radar was successfully tested for the flight test.
In the process of developing airborne radar, the world first created:
- multi-note "transparent" traveling wave tube;
- ultra-low noise small electrostatic discharger;
- three-dimensional large-angle antenna hydraulic system, scanning speed 300 degrees / sec, acceleration 3000 degrees / second 2.
In the "Синтез-10" airborne radar development process, the former Soviet Union for the first time and obtained the following results:
- Component made entirely based on airborne radar developed with a programmable digital signal processing function;
- the onboard When the radar is tested for flying, the trajectory processing method is adopted in the "target search" state, and the calculated value of the target discovery distance is confirmed. For the target with a reflection area of 5 square meters, the distance is more than 200 kilometers;
- using the synthetic aperture antenna to the ground Real-time imaging was performed with a resolution of 7 meters.
The main combination of airborne synthetic aperture radar:
- Antenna. The X-band flat slot single-pulse antenna uses a unique salt bath welding process. The antenna has a diameter of 960 mm, a thickness of 50 mm and a weight of 13 kg. The antenna gain is greater than 37.5 dB within 6% bandwidth, and the far side lobe rms value does not exceed -50 dB.
- Transmitter. The modular multi-mode wideband transmitter uses a high-power multi-injection "transparent" traveling wave tube amplification chain with an output pulse power of 3.5 kW.
- Signal preprocessor. The programmable signal preprocessor can perform 512-point fast Fourier transform in 340 microseconds with an instantaneous dynamic range of 90 dB and a sidelobe level of minus 60 dB.
- Radar signal processor. The radar signal processor uses a single board machine with a processing speed of one million times per second.
Due to the high cost and complicated technology, the Soviet high-level finally chose the old but lower cost N001, N019 as the configuration of su27 and MiG-29, N001 even after 2010, equipped with Russian SU30M2
