     DETAILED DESCRIPTION OF THE INVENTION  
       [0010]     The antiballistic missile defense system is based on a layered defense system (boost, post boost, reentry). In the post boost phase there is little chance of destroying an enemy missile disguised with countermeasures based on the current system (hit-to-kill). The proposed system is resistant to countermeasures and may track the enemy missile from launch to destination. This robust track provides an increased chance of destroying an enemy missile in any phase.  
         [0011]     Multiwavelength satellites, illuminating satellites and multiwavelength antiballistic missiles may overcome enemy missile countermeasures (i.e. decoys, aerosols, changing trajectory). The multiwavelength antiballistic missile may be guided by the multiwavelength satellites, the global positioning system, the internal sensory system and the internal navigation system. The multiwavelength satellite and the multiwavelength antiballistic missile may consist of a main reflector capable of collimating/focusing a wide selection of arbitrary wavelengths (.i.e. multilayered dielectric reflector). The reflector&#39;s light may then be directed to a particular wavelength sensor by appropriate means (i.e. moveable dielectric mirror, moveable filters). The enemy missile may be viewed at different wavelengths through time division observation. Condition based wavelength selection/fusion may provide more accurate tracking. Closing range target destruction may be based on lidar and internal sensor systems. A sufficient number of multiwavelength satellites may be deployed to observe and track the enemy missile against the blackness of space. This black background may provide a high resolution view of the missile/countermeasures. Countermeasures may be defeated by computer/human analysis of the unique missile trajectory (fixed post boost), wavelength selection to see through the aerosol, behavioral movement of the decoy disguised missile (i.e. missile inside balloon)/decoys (i.e. balloon) under different illumination conditions and rapid trajectory updates to maintain lock on an evasive missile (i.e. trajectory changes post boost). This multiwavelength satellite track may be difficult to break. This detection scheme may be accomplished with the light of day on the enemy missile; but, the enemy missile is more difficult to discern at night. To improve nighttime performance, a series of illuminating satellites with large optical systems may cover the earth. These illuminating satellites may receive the coordinates of the enemy missile from the multiwavelength satellites. The illuminating satellites may then rotate into position focusing the light (i.e. sun, led, laser) onto the enemy missile/decoys. This allows the multiwavelength satellite to observe the highlighted missile/decoys against the blackness of space. Under these conditions, the multiwavelength satellites may direct the multiwavelength antiballistic missile to the target. The multiwavelength antiballistic missile may also carry high power explosives, an electromagnetic pulse weapon or a nuclear weapon to ensure destruction or to take out multiple missiles/decoys. The multiwavelength antiballistic missile may use an appropriate launch method (i.e. chemical rocket, electromagnetic launch with chemical maneuvering rockets). The electromagnetic launch may cost a great deal up front; but, it has the capacity to rapidly launch vast quantities of low cost multiwavelength antiballistic missiles. This may provide multiple opportunities to destroy an enemy missile. The electromagnetic launcher may also boost space hardware. Anything launched electromagnetically will have to be designed to endure high acceleration forces, high temperatures and high electromagnetic fields. Each multiwavelength antiballistic missile may deploy a series of smaller similarly configured missiles for taking on multiple enemy missiles. A larger boost rocket may launch multiple standard size (or various size) multiwavelength antiballistic missiles at the same time.  
         [0012]     Several light generating methods may be available on an individual illumination satellite. One or more of the light generating methods may be employed simultaneously by the same illumination satellite. The illumination satellites may serve to improve system tracking performance during both the day and night. The illumination satellite may bathe the enemy missile in ultraviolet/visible/infrared/any wavelength light. The light may illuminate a very small area to a very large area. The intensity of the light may vary from zero to very intense (i.e. laser). Even if a laser does not destroy the enemy missile, it may become a highly luminous target. Multiple illuminating satellites may target one enemy missile (i.e. visible light for viewing, laser light for illuminating/destroying) or may work cooperatively in locating an enemy missile. Accurate tracking ability of multiwavelength or illumination satellites is a function of the satellites ability to position itself in real time. The two main methods of positioning satellites are thrusters and reaction wheels. The thrusters may be designed to emit from zero to maximum thrust in exceptionally tiny increments. The lifetime of the thruster satellite is limited by the fuel supply. The remnants from the burned fuel may be appropriately expelled to minimize distortion of the image and to minimize interference with the illumination beam. The vibration resulting from nozzle thrust may be minimized by design. A reaction wheel satellite may be designed with one or more sets of axes. Each axis may control one or more appropriately specified reaction wheels. By selecting an appropriate range of inertia/mass values for the wheels, very fast to extremely slow and precise movements may be accomplished by the satellite. The reaction wheel may be powered by solar panels with an energy storage system. Such a reaction wheel satellite coupled with a guide star track/handoff, a gyroscope/accelerometer, interferometer based encoders, torque sensors, sinusoidally driven zero cog precision motors, high quality ball bearing/magnetic bearing system and an excellent control algorithm may provide the greatest degree of tracking stability. These same design principles may be applied to the thruster satellite. The vibration from satellite components (i.e. cooling system, pumps, motors, temperature difference) may be minimized by design or turned off during critical periods. It is this type of accuracy that is necessary to enable the satellites to maintain an unshakable lock on the enemy missile. All multiwavelength satellites, illumination satellites and multiwavelength antiballistic missiles must be thoroughly protected from both nuclear/cosmic radiation and nuclear electromagnetic pulses.  
         [0013]     A cooling system may be established for any laser system components that are exposed to the intense laser radiation (i.e. laser crystal, laser mirrors, lenses, filters, optics, or any components). An arbitrary pattern of channels may be placed in all heat stressed materials through which may be pumped a cooling medium. Only a small fraction of the laser light that passes through the material passes through the cooling medium. Thus there is minimal interaction with the laser beam. To provide effective cooling the medium does not absorb the laser light. The cooling medium may be pumped to an effective radiator to dispose of the excess heat. Different mediums may be used for the same piece of material. The cooling mediums may be chosen to actively modulate the beam under certain conditions.
