侦察卫星就是窃取军事情报的卫星。它利用光电遥感器或无线电接收机,搜集地面目标的电磁波信息,用胶卷或磁带记录下来后存贮在卫星返回舱里,待卫星返回时,由地面人员回收;或者通过无线电传输的方法,随时或在某个适当的时候传输给地面的接收站,经光学、电子计算机处理后,人们就可以看到有关目标的各种信息。下面是美国侦察卫星“眼”中的军事目标。 Reconnaissance satellites are satellites that steal military intelligence. It uses optical telemetry or radio receiver to collect the electromagnetic wave information of the ground target, recorded in film or tape and stored in the satellite return capsule until the satellite returns, by the ground staff to recover; or by radio transmission, at any time Or at an appropriate time to the ground receiving station, after optical, electronic computer processing, people can see a variety of information about the target. Below is the military objective of the U.S. reconnaissance satellite “Eye.”
