航天侦察就是利用航天器上的光电遥感器和无线电接收机等侦察设备获取侦察情报的技术。航天侦察是现代战略侦察的主要手段。遥感器和无线电接收机所获得的目标信息以不同方式传回地面,经加工处理和判读分析后,作为决策者判明敌情和制定对策的重要依据。 Spacecraft reconnaissance is the use of spacecraft on optoelectronic sensors and radio receivers and other reconnaissance equipment to obtain reconnaissance intelligence technology. Space reconnaissance is the primary means of modern strategic reconnaissance. Target information obtained by remote sensors and radio receivers is transmitted back to the ground in different ways. After being processed and interpreted, it serves as an important basis for decision-makers to identify their enemy’s situation and formulate countermeasures.
