I don't see why you're making fun of this; it made sense to me. From
certain very specific directions a cone can look like a sphere. From all
directions, a sphere looks like a sphere. Most other decoy shapes will,
in some orientation, not look like a possible shape of a cone. A sensor
must respond to all possible signatures of a cone. A sensor must not
respond to all possible shapes of a decoy. The intersection of [sensor
signatures] with [cone decoy profiles] is less than the intersection of
[sensor signatures] with [sphere decoy profiles].
A sphere [decoy] is more like a cone [missile] than a cone [decoy] is like
a cone [missile].
A sphere is more like a cone than a cone is like a cone.
Makes sense to me...
