God! .Can see the headlines of the spy satellite.

<P> The most advanced military spy satellite images enough to see the soldiers in the hands of the gun on the ground model, but also saw the newspaper headline; but to say that today's world is no secret, is still exaggerated. .</ P> <P> States military spy satellites (also known as satellites) directly under the image of a top secret. .The resulting sense of mystery, so that the myth of the satellite images spread around..多尔迈德尔 as an American journalist reported: one running at 160 km altitude orbit of the U.S. spy satellite photographed a Russian warship, photos to enlarge later, clear enough to see the bolts on the deck, while the station .next to a sailor in reading a newspaper, header, "Pravda," the words it has also vividly remembered. .One will write a novel origin, said high-tech spy satellites in the United States 24 hours under the watchful eye of the world today has been no secret to hide. .</ P> <P> let the world shocked by this description. .The fact is that so? .</ P> <P> satellite "eyes" </ P> <P> satellite images are based on the last special film cameras, according to the film after the capsule back into the ground, so for a long period of image .. .Commonly known as satellite photos of these photos. .</ P> <P> but nearly 20 years of satellite images delivered to users are mostly using a special number (digital) camera to obtain digital images and more information can be directly sent to the earth with radio waves, so to obtain images from a number of cycles .months, days significantly reduced to hours or even less, but also easy to use computer processing and distribution. .</ P> <P> but the digital information to a computer or other device to see the corresponding image, it is now generally referred to satellite images and satellite photos are no longer called. .Also renamed the images corresponding reconnaissance satellite. .</ P> <P> ground resolution optical imaging satellite technology to measure an important indicator of the level. .Resolution refers to the image, the minimum distance separating two objects, rather than to see the minimum size of objects. .For example, Google "satellite map" on the resolution of about 1 meter. .1 meter apart that two people or more, you can see in the image of two separate people, when two people from the less than 1 meter, the two images will be combined into one, the image can only see 1 .points. .</ P> <P> a plane size of about 1 meter target at 1 meter ground resolution image, just a pixel, in general, no matter how many times the image magnification, it is just a pixel. .But the reaction from the image resolution is not the ground on the "see" the minimum size of objects on the ground, 1 meter resolution satellite image in visible light, can see the vertical projection of the size much smaller than 1 meter, they just can not see .size is much larger than 1 meter in the green tents of green. .</ P> <P> In most cases, people are used to obtain optical imaging satellite ground information. .These satellites have a specialty focus camera, the focal length is 2 meters above the focus has been the largest up to 6 meters, the equivalent of a large multiple of the telescope. .United States, "QuickBird" satellite images and other civilian high-tech 0.6 to 1 meter resolution, you can see Tiananmen Square, less than 0.5 meters in the vertical projection of visitors, the Beijing road width of less than 0.2 meter lane lines, in the light and .In good weather you can even see the thin high-voltage lines. .</ P> <P> high-tech U.S. military satellite images of course, far higher than the performance of civilian satellites, see Russian warships large bolts on the deck really no problem. .</ P> <P> commonly used optical imaging satellite elliptical orbit, such as the U.S. military "KH-12 (Advanced KH)" Visible spy satellites will run 322 km at perigee, apogee 966 km sun-synchronous orbit. .Satellite images to its orbital perigee run, the film is the highest resolution images of the ground below, its value is the highest resolution satellite images. .But most of the target area not just in the image below the orbit perigee on the ground, so the satellite images are often forced to distance from the target area on the ground tilt image, the result of satellite images taken far below the resolution of most images .its highest resolution. .</ P> <P> under a more exciting: the most talked about laptop in 2005 [for fine] </ P> <P> most mysterious of the strangest, most incredible of all in Discovery </ P> < .P> </ p>.
