Chinese researchers announced that the satellite they have developed using this advanced technology has performed 100 times higher than traditional telescopes and leading spy cameras. According to South China Morning Post, this innovative system, Chinese The Academy of Sciences was developed by the Aviation Information Research Institute and the findings were published in the 52nd of the Chinese Journal of Lasers magazine (Volume 3).
Two and three -dimensional images
This is strong satellitehas a wide range of applications. In particular, foreign satellites can be monitored at an unreachable detail level. In the tests performed in Lake Qinghai in northwest of China, two and three -dimensional images were obtained by using a laser radar system called Lidar (Sal) with synthetic openness.
The power of raft technology
The synthetic clarity Lidar (raft) produces much higher resolution images than other beam scanning radar systems using the movement of an object. The traditional synthetic opening radar (SAR) systems were based on microwave radiation with longer wavelengths, which led to low -resolution images. However, China’s new system works at the optical wavelength. These wavelengths are much shorter than the microwaves, so it provides sharper and clearer images.
A big difference to previous technologies
This development leaves the past milestones behind. For example, in a test conducted by Lockheed Martin in 2011, only 2 centimeters from 1.6 kilometers away was reached. In China, a resolution of 5 centimeters was obtained from 6.9 kilometers away. The new system, on the other hand, revolutionizes this field by offering millimeter resolution from distances exceeding 100 kilometers.
Technical Innovation: Micro Lens Series
The Chinese team divided the laser beam into a 4×4 micro lens series and increased the optical opening of the system from 17.2 millimeter to 68.8 millimeters. This innovation increased the performance of the system by overcoming the historical limitations between the field of view and the openness dimension.
Does bad weather affect conditions?
The tests were performed in almost flawless weather conditions with fixed wind and low cloud cover. However, experts warn that bad weather or atmospheric deteriorations may adversely affect the sensitivity and reliability of the system. This raises the question of how effective technology will be in real world conditions.
