ABSTRACT:
A Method and Apparatus for Surgical High-speed Follower Jamming Based on Selectable Target Direction is disclosed. The system and method of the present invention automatically detects and jams sudden, short duration communications signals in near real time, in a compass direction selected by the user on the battlefield. Such a system is unique in the number and type of input parameters it uses to allow the operator to tailor its jamming results. The system solves the efficiency, fratricide, and latency issues of prior art systems and greatly enhances the operational capabilities of the modern military unit by allowing the unit to kill all enemy transmitters in any specified sector of the battlefield. The system embodies the addition of real time direction-finding methods to the invention of application Ser. No. 10/912,976. The system has all the abilities of the system described in the '976 application, but is further able to automatically detect the direction of the incoming signals (relative to the user), and thereafter to add that information to the jamming decision logic. Finally, the preferred system provides a user interface that enables operators to set up the system to jam on enemy signals based upon the direction to those enemy signals.
