Nope, sonic is just that, and the sonic you need for that is likely not at 60k feet. However, they recently found burried cities in Egypt using ground penetrating radar.
The "image" resolution for that is probably on the order of 10 meters. Good enough to detect a city and its streets, but hopelessly inadequate to image the interior of a launch silo.
