China’s invention turns small drone into stadium-sized UFO on radar to fool enemies

A team of scientists in China worked on a significant innovation that can be used to fool the country’s enemies during wars. The team claims that its latest innovation can turn a drone with radar reflector – roughly the size of an iPad tablet – into an unidentified flying object (UFO) as big as a sports stadium on radars.

This is aimed at fooling enemy radar operators during wars and strengthen China’s position in electronic warfare technology.

Earlier, military researchers have focused on developing modern stealth technology to hide its flying objects from enemy radars. However, the latest Chinese innovation can be effectively used to divert enemies and waste their crucial time during military conflicts.

Giant flying saucer in mid-air shows on radar

The latest study, published in Chinese-language journal Radar Science and Technology, maintains that tablets would appear on radar suddenly looking similar to a giant flying saucer in mid-air will shock enemy radar operators.

Researchers created a radar cross-section (RCS) – the echo produced by a target’s power output – for the tablet measuring 5,240 square metres (56,400 sq ft). By powering up the radar reflector as it was carried by a drone, the researchers found it could “significantly increase RCS to mask the characteristics of real targets, effectively achieving tactical goals such as anti-reconnaissance and anti-attack”, reported SCMP.

Chen Qiang, associate researcher at the National University of Defence Technology’s School of Electronic Science and Technology who led the research team, stated that the effect was achieved with “unprecedented efficiency”.

Swarm of these drones can overwhelm radar screens

Scientists believe that a swarm of these drones can overwhelm radar screens, leaving their operators stunned and in a state of shock.

Researchers maintained that the RCS is measured by the amount of power generated by a target. When scattered equally in all directions, the energy output produces an echo of the same size on the radar screen, according to scientists.

Scientists conducted various military tests of the prototype, which showed that it can effectively enhance and reflect electromagnetic waves coming from different directions.

Device displayed impressive performance when operating in the X-band

Researchers maintained that the device displayed a particularly impressive performance when operating in the X-band, which is commonly used for weapons control and target tracking.

They claimed that the method only requires powering the amplification module, eliminating the need for the generation and analysis of electromagnetic signals, thus offering the advantages of miniaturization and scalability, reported SCMP.

Innovation inspired by a patent filed in 1959

A patent filed in 1959 by Lester C. Van Atta, a radar expert at what was then the Hughes Aircraft Company, inspired the latest innovation.

Van Atta introduced a unique array antenna, designed to ensure that the waveform and path of incident coincided perfectly with the reflected waves. To work, the array’s aperture needed to be much bigger, which is why the idea stayed on paper for 60 years.

By applying an electrical current to the Van Atta array, the Chinese scientists were able to significantly enhance the device’s RCS-boosting capabilities, according to the researchers.
