Uncover mysterious figures in China

Mysterious structures recently discovered by Google Maps in the Gobi desert in China are likely to be the fulcrum for directional satellites.

In the past few days, the press, from the orthodox to the unorthodox, surmised that it could be places to test nuclear weapons and street maps in Washington DC, TP. New York, or even the alien messages.

But it seems that these drawings are used for Chinese spy satellites oriented. This is the opinion of engineer Jonathon Hill at Arizona State University - where many cameras are used in NASA's Mars missions. Hill studied the surface images of Mars sent by exploration and satellite robots, as well as data collected by NASA's earth-based flying tools.

Mysterious structures recently discovered by Google Maps in the Gobi desert in China are likely to be the fulcrum for directional satellites.

The system of zic zag white lines in 2 pictures - the strangest among the desert structures - are the targets of reconnaissance satellites. Satellite cameras focus on these 1km-wide and 2km-long structures to navigate the universe.

China has long been known to operate detective satellites, and many other countries, including the US, are still doing so.

White lines about 20m wide create those structures not to be made of reflective metal like many news sites say.'It is possible that the lines are painted rather than white powder or chalk to prevent the wind from blowing , ' Hill said.

Orientation targets are larger than normal, indicating that satellite cameras are being used to identify low-resolution ground targets.

Another strange image taken not far away shows a structure similar to Stonehenge."It can be fairly certain that this is the goal for satellite radar devices ," Hill said. 'Because the amount of radar signals sent to the ground depends on the degree of roughness of the surface, they may be experimenting to create areas around the surface that are sufficiently bumpy to hide part of the plane'.

In other words, the Chinese military can use radar devices to send signals to the ground at the target, and determine the amount of radar signals sent back to them from fighter jets. , as well as how much of the signal is obstructed by objects on the ground arranged in the same structure as the Stonehenge.

Since the first pictures of the Gobi desert images have been released, readers of Gizmodo blog have discovered some other interesting structures in China .

From here, the country's radar experts can learn how to avoid the country's military operations being detected by foreign satellites, as well as finding ways to detect hidden targets in other countries. However, metal-based surfaces will increase the amount of radar signals back to the ground and make full concealment very difficult.

Since the first pictures of the Gobi desert images have been released, readers of Gizmodo blog have discovered some other interesting structures in China. According to Hill, one of such structures seems to be a test site for weapons, possibly to test explosives. Another giant structure looks like the Yagi antenna network. Devices like these can be used for many purposes, such as monitoring the weather and studying the upper atmosphere.
