초록 ▼

A directional warning system and a method of warning of friendly forces. In one embodiment, the system includes: (1) a conductive shield having an opening at an end thereof and a radio frequency absorptive material located on an inner surface thereof, (2) a Luneberg lens located within the conductive shield and (3) a plurality of feed horns located proximate a portion of the Luneberg lens that is distal from the opening and arranged relative thereto based on a zone-of-interest with which the directional warning system may be associated.

대표청구항 ▼

What is claimed is: 1. A method of warning of friendly forces, comprising: projecting a plurality of beams from a directional warning system including: a conductive shield having an opening at an end thereof and a radio frequency absorptive material located on an inner surface thereof, a Luneberg lens located within said conductive shield, and a plurality of feed horns located proximate a portion of said Luneberg lens that is distal from said opening and arranged relative thereto based on a zone-of-interest with which said directional warning system may be associated; and generating a warning based on a number of said beams received. 2. The method as recited in claim 1 wherein said plurality of beams differ from one another to allow said plurality of beams to be discriminated. 3. The method as recited in claim 1 wherein said generating is carried out in a receiver located proximate a zone-of-interest. 4. The method as recited in claim 1 wherein said generating comprises: transmitting responses to said beams with a transponder located proximate a zone-of-interest; and generating said warning based on a number of said responses. 5. The method as recited in claim 1 wherein said plurality of beams intersect based on a zone-of-interest. 6. The method as recited in claim 1 further comprising disabling a weapon based on said number. 7. The method as recited in claim 1 wherein each of said plurality of beams has a 3 decibel width of about 7°. 8. The method as recited in claim 1 wherein each of said plurality of beams has a null-to-null width of about 14°.
