System for destroying ballistic missiles
First Claim
1. A system for intercepting targets having predictable flight trajectory, comprising:
- (i) a platform carrying at least one interceptor missile;
the interceptor missile includes a seeker unit, propulsion system, steering system, and target destruction capability system all communicating with a processor device;
said processor device is further coupled to a data link for communicating with at least said platform;
(ii) the processor device, in response to launching of said interceptor missile, for controlling said steering system and propulsion system for steering said missile in at least the following flight modes;
(a) approach mode, wherein said interceptor missile closes on said target;
(b) trajectory matching mode wherein a velocity vector of the interceptor missile is modified to substantially match a predicted trajectory of the target so that the interceptor missile moves in the same direction as the target in a relatively small closing velocity with respect to the target; and
(c) end game mode wherein the interceptor missile is maneuvered to a distance sufficiently close to the target whereby said target destruction capability system will destroy the target on activation.

Abstract
A system for intercepting targets having predictable flight trajectory, the system comprising a platform carrying an interceptor missile which includes a seeker unit, propulsion system steering system and destruction capability system, all communicating with a processor device. The processor device is further coupled to a data link for communicating with the platform. In response to launching of the intercepting missile, the processor device controls the steering system and propulsion system for steering the missile in one of the following flight modes: (a) approach mode, wherein said intercepting missile closes on said target; (b) trajectory matching mode wherein the interceptor velocity vector is modified to bring the trajectory of the interceptor to match the predicted trajectory of the target so that the interceptor moves in the same direction as the target in a relatively small closing velocity with respect to the target; and (c) end game mode wherein the interceptor is maneuvered to a distance sufficiently close to the target whereby the target destruction capability can be activated efficiently.
