Abstract
A system for defeating a threat posed by a guided missile. The system includes a broad band light source with a beam width of less than 4°, a DIRCM control system, a missile warning system, and a missile tracking system. The DIRCM control system is configured to aim a beam produced by the light source. The missile warning system is configured to supply the DIRCM control system with a first trajectory of the missile. The missile tracking system is configured to supply the DIRCM control system with a second trajectory of the missile, which is more accurate than the first trajectory.
Claims22
A system for defeating a threat posed by a guided missile comprising:
- a) a broad band light source with a beam width of less than 4°;
- b) a DIRCM control system, configured to aim a beam produced by said light source;
- c) a missile warning system configured to supply said DIRCM control system with a first trajectory of the missile;
- and
- d) a missile tracking system configured to supply said DIRCM control system with a second trajectory of the missile, said second trajectory being more accurate than said first trajectory.
A method for neutralizing the threat posed by a guided missile comprising:
- a) detecting the guided missile;
- b) detecting a trajectory of the guided missile;
- and
- illuminating the guided missile based on said trajectory with a broad band light source having a beam width of less than 4°.
A system for defeating a threat posed by a guided missile comprising:
- a) a broad band light source with a variable beam width;
- b) a mechanism for varying said beam width of said light source;
- c) a DIRCM control system, configured to aim a light beam produced by said light source and further configured to control said mechanism for varying said beam width;
- d) a missile warning system configured to supply said DIRCM control system with a first trajectory of the missile;
- and
- e) a missile tracking system configured to supply said DIRCM control system with a second trajectory of the missile, said second trajectory being more accurate than said first trajectory.
A method for neutralizing the threat posed by a guided missile comprising:
- a) detecting the guided missile;
- b) determining a first trajectory of the guided missile
- c) illuminating the guided missile based on said first trajectory with a light beam from a broad band light source, said light beam having a first beam width;
- d) substantially concurrently with c, initiating tracking of the missile with a missile tracking system, said missile tracking system configured to determine a second trajectory of the guided missile, said second trajectory being more accurate than said first trajectory;
- and
- e) illuminating the guided missile based on said second trajectory with a light beam from said broad band light source, said light beam having a second beam width.
