If you follow the news about the war and defense industry, you probably know that there are a number of stealth jet fighters that are difficult or impossible to detect by conventional radars such as the F-22 Raptor and the F-35 Lightning II by Lockheed Martin.
However, scientists from China have recently been reported to have discovered that although radars from the ground are ineffective, the use of satellites from space seems to be able to detect these stealth fighter jets.
By using Starlink satellites, they have successfully detected stealth targets in the South China Sea, using a DJI Phantom 4 Pro drone as a simulation of a fighter jet due to its design that closely resembles a stealth fighter jet.
These scientists use the Starlink satellite to detect changes in electromagnetic signals from the satellite, and scan those changes to determine which objects enter the path of the satellite's electromagnetic signal.
Starlink is now reported to be the company with the largest number of satellites in the world, and the electromagnetic radiation emitted by these satellites allows scientists to detect objects hovering in the air where the company's satellites operate.
Although the DJI Phantom 4 Pro drone comes in a small size, reports say that these Chinese scientists can detect changes as small as movement and changes in terms of rotor speed and so on, even at low altitudes.
For now, the technology of detecting stealth objects through satellites is something very new and has yet to be used for defense and military purposes, but it is expected that within a few years, the Chinese government will come up with the ability to detect stealth fighter jets in the air. without any problem.
