But for the global,around-the-clock radar coverage that the Pentagon wants--a system that would not risk pilots'lives or intrude in foreign airspace--a constellation of two dozen or more high-powered satellites in low Earth orbit would be needed. 但如果要实现五角大楼所希望的覆盖全球的昼夜雷达监测，则需要在低地球轨道设置至少20多颗高性能卫星群。这种全球性的昼夜雷达监测，将使飞行员无须冒生命危险，也不会侵犯别国领空。
For example,the same group of microsatellites could be initially widely spaced to provide worldwide radar coverage,and then within hours moved closer together to conduct finetoothed searches of smaller areas. 例如，一组微型卫星原本分散分布以提供全球雷达监测，但在几个小时之内就可以靠拢到一起，对小区域进行更细致的测绘。
