Abstract
An apparatus and method is described for generating an electromagnetic, or acoustic field by use of a number of field sources in order to produce a field anomaly at a known target location. The field anomaly is characterized by having a wavefront at the target location that has a predetermined desired orientation so that at the target location the field appears to emanate from a different direction to that perceived at field locations away from the target.
Claims18
A projectile defense computer software product for execution by one or more electronic processors of a projectile defense system for producing an electromagnetic or acoustic field anomaly having a desired orientation at a target location, said computer software product including instructions to process
- the location of a number of field sources of the projectile defense system, and
- the target location;
- and
- the desired orientation of said anomaly
- to thereby produce signal parameters for said system to drive the field sources to produce the electromagnetic or acoustic field anomaly at the target location including a wavefront of the desired orientation to thereby mislead a hostile projectile approaching the target location.
A projectile defense system comprising:
- a projectile tracking system for tracking a hostile projectile;
- a target localisation interface responsive to the projectile tracking system and arranged to generate target location data therefrom;
- a signal and phase generation processor arranged to process the target location data to thereby calculate parameters of a field anomaly characterized by a wavefront of a desired orientation for presentation to the hostile projectile;
- and
- a plurality of transducers under control of the signal and phase generation processor to present the field anomaly to said projectile and thereby mislead the hostile projectile.
A projectile defense method including:
- tracking a hostile projectile to determine a target associated therewith;
- operating a number of transducers to produce a field anomaly characterized by a wavefront of a desired orientation within range of sensors of said hostile projectile to thereby mislead said sensors to mistake a phantom target caused by the field anomaly for the target.
