Abstract

The disclosed system for cooperative engagement generally includes a control system in communication with an actuation system, an effector system, a sensor system and a communications interface. Disclosed features and specifications may be variously controlled, adapted or otherwise optionally modified to realize improved distributed designation and/or engagement function. Exemplary embodiments of the present invention generally provide cooperative designation and engagement of targets for air-, land-, sea- or space-based weapon systems.

Claims

1. A method for distributive coordination among a plurality of autonomously controlled agents to affect at least one target, said method comprising the steps of:

composing a target list, said target list comprising a plurality of targets;

providing the target list to each of the plurality of autonomously controlled agents;

selecting a target for engagement, wherein each of the plurality of autonomously controlled agents is configured to;

independently rank the targets within the target list;

independently select its own target based on a set of target selection criteria and create a reservation on the selected target; and

communicate the reservation of the selected target to at least one other of the plurality of autonomously controlled agents; and

affecting the reserved target.

2. The method of claim 1, wherein each of the plurality of autonomously controlled agents comprises at least one of a sensor and a detector to locate at least one target of interest.

3. The method of claim 2, wherein at least one of said detector and said sensor is configured to locate at least one target that is closer than a maximum sensing range.

4. The method of claim 1, further comprising the step of providing location information to each of the plurality of autonomously controlled agents, said location information corresponding to at least one target located outside at least one of said detector and said sensor maximum sensing range.

5. The method of claim 1, wherein each of the plurality of autonomously controlled agents further comprises at least one onboard effector.

6. The method of claim 5, further comprising the step of employing said effector when a target is in range.

7. The method of claim 5, wherein said effector comprises at least one of a weapon and an agentic arm.

8. The method of claim 1, further comprising the step of receiving a reservation communication from one of the plurality of autonomously controlled agents.

9. The method of claim 1, wherein each of the plurality of autonomously controlled agents at least one of tracks a target and designates a target while deploying a weapon, and each of the plurality of autonomously controlled agents maintains said tracking and designation until the weapon hits the target.

10. The method of claim 1, wherein the target selection criteria includes at least one of a target reservation from a second autonomously controlled agent from the plurality of autonomously controlled agents and a target valuation based on at least one of a scoring function and a prioritization scheme.

11. The method of claim 10, wherein said scoring function comprises a linear combination of a plurality of metrics.

12. The method of claim 11, wherein said metrics comprise a weighting function configured to at least one of increase and decrease said metric'"'"'s contribution to the scoring function.

13. The method of claim 11, wherein a metric to be minimized is the distance between the agent and the target.

14. The method of claim 11, wherein a metric to be minimized is the distance between the target and an engagement goal of the target.

15. The method of claim 11, wherein a metric to be maximized is the distance from a target to the nearest reserved target.

16. The method of claim 11, wherein a first autonomously controlled agent predicts the scores the second autonomously controlled agent will obtain for each target, and said first autonomously controlled agent chooses a target whose predicted score of said second autonomously controlled agent is not the highest of said scores.

17. The method of claim 11, wherein at least one of:

each of the plurality of autonomously controlled agent has a range corresponding to a maximum firing range of a weapon;

each of the plurality of autonomously controlled agent is configured to reserve at least one of a single target at a time and at least a plurality of targets at once;

each of the plurality of autonomously controlled agent affects said target when said target is in range;

each of the plurality of autonomously controlled agent affects said target when any valid target enters a predetermined perimeter; and

each of the plurality of autonomously controlled agent releases its reservation.

18. The method of claim 1, further comprising the step of providing an actuation system, said actuation system response to a control system that is configured to maneuver said agent.

19. The method of claim 1, further comprising the step of providing a communications interface, said communications interface configured to communication at least one of reservation and positioning data.

20. A method for distributive cooperative engagement of a target between a first autonomously controlled agent and a second autonomously controlled agent, said method comprising the steps of:

providing each of the first and second autonomously controlled agents with a sensor system adapted to collect targeting information;

providing each of the first and second autonomously controlled agents with a control system in communication with said sensor system, wherein said control system is adapted to create a target reservation based on at least one of said targeting information and a set of at least one of targeting and engagement criteria;

providing each of the first and second autonomously controlled agents with a communications interface in communication with said control system, wherein said communications interface is adapted to communicate the target reservation from the first autonomously controlled agent to the second autonomously controlled agent; and

providing each of the first and second autonomously controlled agents with an effector system in communication with said control system, wherein said effector system is adapted to affect a target.

21. The method of claim 20, further comprising the step of providing an actuation system to each of the first and second autonomously controlled agents, said actuation system responsive to the control system and adapted to maneuver each of the first and second autonomously controlled agents.
