Leaked Pentagon docs show the shot-down Chinese spy balloon may have had a feature known as 'synthetic aperture radar' that can see through certain materials, WaPo reports

The Chinese balloon, nicknamed Killeen-23, could have had technology able to help with three-dimensional reconstructions of objects on the ground.

So spooky :specter: so very benignly spooky. :specter-global:

    Nah, they just use False Color (infrared and whatnot) and SAR (microwaves can penetrate clouds and bounce back, allowing you to 'see' through it).

    Highly recommend these two NASA pages for learning more:

    • https://earthobservatory.nasa.gov/features/FalseColor
    • https://www.earthdata.nasa.gov/learn/backgrounders/what-is-sar

    This example of False Color for a satellite image of Bangor is a good example , the cloud obscures the northern part of the city under red light, but you can see 'past' it if you look at the shortwave infrared light.
