What might it be spying on?
According to Layton, the suspected Chinese balloon is likely collecting information on US communication systems and radars.

“Some of these systems use extremely high frequencies that are short range, can be absorbed by the atmosphere and being line-of-sight are very directional. It’s possible a balloon might be a better collection platform for such specific technical collection than a satellite,” he said.

“其中一些系统使用极高的频率，这些频率很短，可以被大气吸收，视线非常定向。对于这种特定的技术收集来说，气球可能是一个比卫星更好的收集平台，”他说。—在 edition.cnn.com/2023/02/02/asia/us-china-spy-balloon-mission-intl-hnk-ml/上阅读
