a 1 km object at 20 million miles equals a 12 meter object at 250,000
miles, or a 12 cm object at 2500 miles. Given a limited set of launch
areas and impact areas, there are defined loci of terminal trajectories
to scan.

Given a known launch area, and impact area, there is a limited set of
targeting solutions to look for. Given this, there are limited areas
that can be scanned for erroneous energy signals.
