The blue sky event Air show review | Luneburg lens technology at China air show

The 14th China International Aviation and Aerospace Expo will be held in Zhuhai, Guangdong Province, from Nov 8 to Nov 13, 2022. More than 740 companies from 43 countries and regions participated in this year's Airshow, showcasing the latest achievements in aerospace technology. Airshow China has become a grand gathering to showcase the development level of international aviation and aerospace science and technology, and a shining name card of China's charm as an aerospace power to the world.


The application of radar in aviation and its military role in aircraft are of far-reaching significance. The EAHISON subsidiary Fushun Tianji Luneburg Lens appeared at the Airshow, demonstrating the international advanced level of the new generation Luneburg lens technology in depth, attracting leaders, experts and industry colleagues to stop and visit, and the scene was warm.


At present, Fushun Tianji Luneburg lens technology has achieved mass production and commercial use with advanced manufacturing technology and mature production technology, and has been commercialized on the scale of 5G network construction. In terms of SAR imaging, it can play a hidden truth and show false effect, and has applied for more than 130 patents of various kinds, making outstanding contributions to local economy and national defense construction.

Luneburg lens is a kind of lens. Due to its converging characteristics on plane beam, when the radar waves pass through the lens, the radar reflection area of the lens is large. Therefore, Luneburg lens can play a huge role in radar jamming, false targets, electronic countermeasures, target characteristic simulation, identification friend or foe and other applications. The new generation of Luneburg lens technology can greatly save the cost of battlefield construction, improve our combat survivability, jamming enemy radar and reduce the accuracy of enemy attack, and contribute to national defense! The specific application areas are described as follows:

1. Target performance simulation system.

In modern war, the technical investigation is mainly based on optical imaging and radar imaging. The programmable Luneburg lens reflector array is composed of Luneburg lens. Under the control of graphics coding computer, the polarization characteristics, reflection efficiency and surface graphic reflection intensity of the lens array can be changed in real time, and the radar reflection characteristics and optical reflection characteristics can be changed. Thus, the SAR imaging structure can be changed, the protected target can be integrated with the environment, and the survival probability of the protected target can be effectively improved.

2. Application scenario of target projectile of air training target aircraft.

The Luneburg lens scatterer is used to magnify the scattering area of radar, simulate the actual combat scene, improve the exercise quality and realize the low-cost target aircraft.

3. In the target concealment application scenario.

In medium and large scale system, the Luneburg lens scatterer can form a large area of radar strong reflection area, so that the enemy can not distinguish the authenticity of the strong reflection area.

4. Application scenario of small missile induction.

The Luneburg lens can simulate the characteristics of large missile radar, disturb or induce the activation of enemy anti-missile devices, effectively consume the number of enemy interceptor missiles and carry out accurate strikes.

5. Fake target application scenario.

The land strategic target has a large area, which can be masked by the Luneburg lens reflector array. Meanwhile, the Luneburg lens reflector array can be combined with the optical false target around the target to deceive the microwave radar and optical detection equipment.

6. Application scenario of maritime omnidirectional radar buoy.

The new generation buoy is made of Luneburg lens reflector, which has the radar reflection ability, so that the radar can detect the buoy beyond the visual range and reduce the occurrence of disasters.

7. Application scenarios of satellite communication antennas.

The stereoscopic multi-beam of Luneburg lens is passive with high gain, and has the characteristics of multi-beam to realize multi-star simultaneous communication and support multi-frequency communication.

8. Lightning school.

The radar station and radar vehicle are calibrated by using the drone to carry the Luneburg lens reflector.

9. Portable low small slow target detection radar.

It can be used for airspace security and battlefield reconnaissance to detect small UAVs entering alert airspace in time, and to investigate ground targets within a certain range.

Although the 14th China Air Show has come to an end, in the future, China will develop from a space power into a space power with more sonorous steps. The maturity of any kind of technology requires a long period of demonstration, application, verification, improvement, and gradually mature. In the process of technological innovation and product upgrading, Fushun Tianji has never stopped. It has been continuously increasing the investment in research and development, constantly overcoming key technical problems, and deepening the lens technology step by step. In the future, Fushun will continue to forge ahead along the road of independent innovation.
