并非所有巡航导弹都是涂的美国空军的兰色。有些巡航导弹涂的是苏联的红色。同美国所能做到的一样,这些红色巡航导弹能从地面雷达波束底下飞行,或从海军特遣部队机载雷达有限探测范围之外飞过。这种新的威胁使得研究开发空基雷达更为紧迫。在1500海里高空的空基雷达能搜索约1700万平方海里的地区,这一面积比亚洲还大。而实现空基雷达系统也就有相应的困难。如果允许雷达波束重扫一个特定场地的 Not all cruise missiles are painted by the U.S. Air Force’s blue. Some cruise missiles are painted Soviet red. As the United States can do, these red cruise missiles can fly under ground radar beams or fly over the limited naval task force airborne radars. This new threat makes research and development of space-based radars more urgent. At an altitude of 1,500 nautical miles, space-based radars can search about 17 million square nautical miles, an area larger than in Asia. The realization of space-based radar systems also have corresponding difficulties. If you allow the radar beam to re-sweep a particular site
