Abstract
A defense system and a method for discriminating between armed
re-entry vehicles and unarmed objects which are in close proximity of
each other. The re-entry vehicles and the unarmed objects are bathed in a
cloud of relativistic electrons with the resulting signatures from
heavy objects, i.e., re-entry vehicles, being imaged directly. Detectors
sense the location and identify of the re-entry vehicles and passes
this information onto a weapons platform for tracking and interception.
First Claim
1. A method of discriminating between
armed, reentry vehicles and unarmed objects in space, said method
comprising:transmitting electromagnetic radiation from the surface of
the earth to the vicinity of the vehicles and objects to accelerate
electrons present in space to create a cloud of relativistic electrons
around said re-entry vehicles and said objects;interacting said
relativistic electrons with said reentry vehicles and said objects to
thereby produce individual signature signals representative of said
individual re-entry vehicles and said objects; anddetecting said
signature signals for discriminating between said re-entry vehicles and
said objects.
