Abstract

A system for communicating with a projectile in flight toward an intended target includes a barrel-launched projectile and a remote receiver. The barrel-launched projectile includes an ordnance portion, an active communications apparatus and an onboard speed control. The active communications apparatus includes an onboard receiver, an electromagnetic wave reception device, and an active transmitter. The electromagnetic wave reception device includes at least one from the group consisting of an antenna and a photo receptor and is configured to receive an electromagnetic signal. The electromagnetic wave reception device is connected to provide a signal derived from the electromagnetic signal to the onboard receiver to deploy the onboard speed control. The active transmitter is connected and configured for transmitting a signal to the remote receiver during flight and before activation of the speed control. The transmitted signal is directed within a cone angle extending in a direction opposite of the barrel-launched projectile'"'"'s flight direction. The onboard speed control includes a shaped explosive charge. Deploying the onboard speed control initiates explosion of the shaped explosive charge. The explosion of the shaped explosive charge adjusts velocity of the barrel-launched projectile.

Claims

1. A projectile capable of impacting a target comprising:

an ordnance portion;

an onboard speed control coupled to the ordnance portion and having a shaped explosive charge, wherein the shaped explosive charge adjusts the velocity of the ordnance portion after firing of the projectile; and

an active transmitter coupled to the ordnance portion, wherein the active transmitter transmits a signal within a cone angle extending in a direction opposite of the projectile'"'"'s flight direction after the projectile has impacted the target.

2. A projectile according to claim 1, further including an active communication apparatus in electronic communication with the onboard speed control, the active communication apparatus having a reception device.

3. A projectile according to claim 2, wherein the reception device is an electromagnetic wave reception device.

4. A projectile according to claim 3, wherein the electromagnetic wave reception device is configured to receive an electromagnetic signal.

5. A projectile according to claim 2, wherein the reception device is configured to receive a signal so as to deploy the onboard speed control.

6. A projectile according to claim 2, wherein the reception device is one of an antenna and a photo receptor.

7. A projectile according to claim 2, further comprising a power supply for providing energy to at least the active communication apparatus.

8. A projectile according to claim 7, wherein the power supply includes a use detection apparatus for activating the power supply after the occurrence of a use event.

9. A projectile according to claim 8, wherein the use event is one of a launch event and an impact event.

10. A projectile according to claim 2, wherein the reception device is configured to receive a signal representative of a distance of the projectile to the target and to communicate the distance to the onboard speed control, and wherein the onboard speed control is configured to detonate the shaped explosive charge when the distance is at or less than a predetermined value.

11. A projectile according to claim 1, further comprising a sensor capable of detecting one or more of a vibration, a motion, a chemical, a biological agent, a nuclear decay particle, a sound, and an electromagnetic signal.

12. A projectile according to claim 1, further including a probe coupled to the ordnance portion, wherein the shaped explosive charge is detonated on contact of the probe with the target.

13. A projectile according to claim 1, wherein the ordnance portion is constructed of an energy absorbing material.

14. A projectile capable of impacting a target comprising:

an ordnance portion;

an onboard speed control coupled to the ordnance portion and having a shaped explosive charge, wherein the shaped explosive charge adjusts the velocity of the ordnance portion after firing of the projectile;

an active communication apparatus in electronic communication with the onboard speed control, the active communication apparatus having a reception device and an active transmitter,

wherein the active communication apparatus is coupled to the rear of the ordnance portion, and wherein the active transmitter transmits a signal within a cone angle extending in a direction opposite of the projectile'"'"'s flight direction after the projectile has impacted the target.

15. A projectile according to claim 14, wherein the ordnance portion is constructed of an energy absorbing material and wherein the energy absorbing material encases a penetration device.

16. A projectile according to claim 14, further including a plurality of light sources in electronic communication with the active communication apparatus, and wherein the active communication apparatus sequentially excites ones of the plurality of light sources.

17. A projectile according to claim 16, wherein the communication apparatus further includes a lens assembly configured to project the light transmitted from one of the plurality of light sources at a first angle and to project the infrared energy transmitted from another of the plurality of light sources at a second angle.

18. A projectile according to claim 14, wherein the ordnance portion and the communication apparatus are arranged such the ordnance portion extends in the direction of flight ahead of the communication portion, and wherein the ordnance portion is sized and configured so that upon impact the communication apparatus is undamaged and attached to the target.

19. A projectile according to claim 14, further comprising a deployable fin configured for slowing the projectile.

20. A projectile according to claim 14, wherein the reception device is configured to receive a signal representative of a distance of the projectile to the target and to communicate the distance to the onboard speed control, and wherein the onboard speed control is configured to detonate the shaped explosive charge when the distance is at or less than a predetermined value.
