Abstract

A targeting munition for a targeting system and method includes a payload including a plurality of shards. At least one of the shards includes a laser diode configured to emit targeting emission in response to the targeting munition impacting an area at or proximate to a target.

First claim

What is claimed is:

1. A targeting munition for a targeting system, the targeting munition comprising:
a payload including:
a plurality of shards, wherein at least one of the shards includes a laser diode configured to emit targeting emission in response to the targeting munition impacting an area at or proximate to a target;
a retention band to retain the plurality of shards prior to the targeting munition impacting the target; and
a band cutter configured to sever the retention band in response to the targeting munition impacting the target, wherein the band cutter is disposed inside of the retention band such that the retention band extends around at least a portion of the band cutter.

2. The targeting munition of claim 1 , wherein each of the plurality of shards includes a laser diode.

3. The targeting munition of claim 1 , wherein the laser diode is configured to emit the targeting emission at a predetermined frequency.

4. The targeting munition of claim 1 , wherein the payload further comprises a battery and a ballast.

5. The targeting munition of claim 1 , further comprising a propulsion system coupled to the payload.

6. The targeting munition of claim 1 , wherein the targeting munition is a 40 mm targeting grenade.

7. The targeting munition of claim 1 , wherein each of the plurality of shards is configured to be ejected a predetermined distance in response to the targeting munition impacting the target.

8. The targeting munition of claim 7 , wherein the predetermined distance is approximately 1 to 3 meters.

9. The targeting munition of claim 1 , wherein the plurality of shards comprises five shards.

10. The targeting munition of claim 1 , wherein at least one of the plurality of shards is configured to land in an upright position such that the laser diode emits the targeting emission toward the sky.

11. The targeting munition of claim 1 , wherein the targeting munition is configured to be deployed from a handheld grenade launcher.

12. The targeting munition of claim 1 , wherein the targeting emission is infrared light.

13. A targeting method comprising:
retaining a plurality of shards within a targeting munition prior to impact with a retention band;
directing the targeting munition toward a target;
severing the retention band on impact at or proximate to the target with a band cutter disposed inside of the retention band such that the retention band extends around at least a portion of the band cutter before the impact; and
emitting targeting emissions from laser diodes of the plurality of shards ejected from the targeting munition upon the impact of the targeting munition at or proximate to the target.

14. The targeting method of claim 13 , wherein said emitting comprises emitting the targeting emission at a predetermined frequency.

15. The targeting method of claim 13 , further comprising ejecting each of the plurality of shards a predetermined distance upon impact of the target targeting munition by the targeting munition.

16. The targeting method of claim 15 , wherein the predetermined distance is approximately 1 to 3 meters.

17. The targeting method of claim 13 , wherein the plurality of shards comprises five shards.

18. The targeting method of claim 13 , wherein said directing comprises deploying the targeting munition from a handheld grenade launcher.

19. A targeting munition for a targeting system, the targeting munition comprising:
a propulsion system; and
a payload coupled to the propulsion system, wherein the payload comprises:
a battery;
a ballast;
a plurality of shards, wherein each of the plurality of shards includes a laser diode configured to emit targeting emission at a predetermined frequency in response to the targeting munition impacting an area at or proximate to a target, and wherein each of the plurality of shards is configured to be ejected a predetermined distance in response to the targeting munition impacting the target;
a retention band to retain the plurality of shards prior to the targeting munition impacting the target; and
a band cutter configured to sever the retention band in response to the targeting munition impacting the target, wherein the band cutter is disposed inside of the retention band such that the retention band extends around at least a portion of the band cutter.

20. The targeting munition of claim 19 , wherein the targeting munition is configured to be deployed from a handheld grenade launcher, and wherein the targeting emission is infrared light.
