Abstract

The present invention is a fire control system. The fire control system comprises a manually aimed gun having a sighting device and a device for acquiring a target. The acquiring device is disposed at a location remote from the gun. The fire control system also comprises a device for determining the trajectory of the target with respect to the gun and providing information relating to the target to the sighting device of the gun such that an operator of the gun can aim the gun with respect to the sighting device to hit the target when the gun is fired. The determining device is in communication with the acquiring device and the sighting device. The present invention is also a fire control method for a minor caliber gun. The method comprises the step of acquiring a target from a location which is remote from the gun. Then, there is the step of determining the trajectory of the target with respect to the gun. Next, there is the step of providing information relating to the target to a sighting device of the gun. Then, there is the step of manually aiming the gun in accordance with the information appearing on the sighting device such that the gun is aimed to accurately hit the target when fired.

Claims

1. A fire control system comprising:

a manually aimed gun having a sighting device;

means for acquiring a target, said acquiring means disposed at a location remote from said gun; and

means for determining a trajectory of the target with respect to the gun and providing information relating to the target to the sighting device of the gun such that an operator of the gun can aim the gun with respect to the sighting device to hit the target when the gun is fired, said determining means being in communication with said acquiring means and the sighting device.

2. A fire control system as described in claim 1 wherein the acquiring means comprises a radar device.

3. A fire control system as described in claim 2 wherein the acquiring means comprises an electro-optical tracker device having a FLIR imaging device and a laser rangefinder.

4. A fire control system as described in claim 3 wherein the acquiring means comprises a day TV camera device.

5. A fire control system as described in claim 1 wherein the trajectory determining means comprises means for tracking the target.

6. A fire control system as described in claim 5 wherein the determining means comprises means for performing a dynamic offset computation on a target track.

7. A fire control system as described in claim 6 wherein the determining means comprises means for determining a position of the electro-optical tracker device with respect to a predetermined reference system.

8. A fire control system as described in claim 7 wherein the determining means comprises means for determining a position of the gun with respect to a predetermined reference system.

9. A fire control system as described in claim 8 wherein the determining means comprises means for determining a position and movement of a vehicle upon which the fire control system is disposed with respect to a predetermined reference system.

10. A fire control system as described in claim 9 wherein the determining means comprises means for determining environmental conditions about the gun.

11. A fire control system as described in claim 10 wherein the determining means comprises a gun operator data entry device.

12. A fire control system as described in claim 11 wherein the determining means provides a reticle to the sighting device, said determining means displacing said reticle such that when the reticle is manually aimed on the target, the gun is aimed to accurately hit the target when fired.

13. A fire control system as described in claim 12 wherein the determining means provides direction of motion symbology on the sighting device based on the direction and magnitude required to correctly aim the gun.

14. A fire control system as described in claim 13 wherein the determining means provides range data on the sighting device.

15. A fire control system as described in claim 14 wherein the determining means includes a stabilization device for maintaining the aim of the gun.

16. A fire control system as described in claim 15 wherein the sighting device of the gun includes a video display monitor.

17. A fire control system as described in claim 16 wherein the determining means comprises means for providing a FLIR image of the target to the video display monitor of the gun.

18. A fire control system as described in claim 17 wherein the acquiring means comprises a control console having a control video monitor.

19. A fire control system as described in claim 18 wherein the gun comprises a fire enable gate which enables the gun for firing only when the gun is correctly aimed to hit the target, said fire enable gate being in communication with said determining means.

20. A fire control system as described in claim 19 comprising means for providing training images to the video display monitor of the gun such that the fire control system can operate in a training mode.

21. A fire control system as described in claim 20 wherein the determining means comprises a computer.

22. A fire control system as described in claim 21 wherein the manually aimed gun has a caliber between 20 and 40 mm.

23. A fire control method for a minor caliber gun comprising the steps of:

acquiring from a location which is remote from the gun, a trajectory;

determining trajectory of the target with respect to the gun;

providing information relating to the target to a sighting device of the gun; and

manually aiming the gun in accordance with information appearing on the sighting device such that the gun is aimed to accurately hit the target when fired.

24. A method as described in claim 23 wherein after the acquiring step, there is a step of tracking the target.

25. A method as described in claim 24 wherein after the tracking step, there is a step of performing a dynamic offset computation on a target track.

26. A method as described in claim 25 wherein the providing step includes a step of providing a displaced reticle on a video display monitor of the sighting device.

27. A method as described in claim 26 wherein the providing step includes a step of providing a FLIR image of the target on the video display monitor.

28. A method as described in claim 27 wherein after the providing step there is a step of enabling the gun when it is aimed in a direction to hit the target.

29. A method as described in claim 28 wherein after the enabling step, there is a step of firing the gun.

30. A method as described in claim 29 wherein the acquiring step includes a step of detecting a target with radar.

31. A fire control system comprising:

a plurality of manually aimed guns each having a sighting device;

means for acquiring at least one target, said acquiring means disposed at a location remote from said guns; and

means for determining a trajectory of the target with respect to each gun and providing information relating to the target to the sighting device of each gun such that an operator of each gun can aim the gun with respect to its sighting device to hit the target when the gun is fired, said determining means being in communication with said acquiring means and each sighting device.

32. A fire control system as described in claim 31 wherein the determining means includes sensor means in contact with the gun to sense where the gun will hit when fired.

33. A fire control system as described in claim 32 wherein the determining means includes tracking means in communication with the acquiring means, and a second computer in communication with the gun and the sensor means to provide a reticle to the sighting device such that when the reticle is aligned with the target, the target will be hit when the gun is fired.
