各国军用间谍卫星(也称侦察卫星)影像一直属最高机密。由此产生的神秘感, 令有关卫星影像的神话四处流传。如美国记者多尔·迈德尔的一篇报道称：一颗运行在160公里高度轨道上的美国侦察卫星拍摄到一艘俄罗斯战舰,照片放大以后, 清楚得可以看到甲板上的螺栓,而站在旁边的一个水兵在看报纸。报头的《真理报》字样居然也历历在目。一位写小说出身的中将说,在美国高科技间谍卫星24小时的严密监视下,今天的世界上已经没有任何秘密可以隐藏。这样的描述让世人震惊。事实是这样的吗? 卫星的“眼睛”过去影像卫星都是采用特制的胶片相机,照完后的胶片装入返回舱送回地面,所以获取影像的周期很长。这些照片俗称卫星照片。但近20年交付用户的影像卫星大都是采用特制的数字(数码)相机,获取的图像
The images of military spy satellites (also known as reconnaissance satellites) of various countries have always been the highest secrets. The resulting sense of mystery, so that the myths about satellite images everywhere. As reported by U.S. journalist Dolme Meade: A U.S. reconnaissance satellite running on a 160-kilometer orbit of a Russian warship was photographed. After the photos were enlarged, the bolts on the deck were clearly visible, while the station A sailor beside was reading the newspaper. Header of the “Pravda” actually actually vivid in mind. A lieutenant who wrote a novel said that under the close surveillance of a 24-hour U.S. high-tech spy satellite, there are no secrets in the world today. This description shocks the world. Is this the case? The “eyes” of the satellites In the past, all the imaging satellites used a special film camera. After the film was loaded into the return capsule and returned to the ground, the period for acquiring images was very long. These photos are commonly known as satellite photos. However, most of the video satellites delivered to users in the past 20 years are images acquired using a specially designed digital (digital) camera
