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.
