System and methods for countering satellite-navigated munitions
A defense system that receives information regarding an incoming object(s), then automatically coordinates spoofing or jamming of SATNAV signals potentially used by the incoming object(s) while also informing friendly systems of the spoofing or jamming of SATNAV signals.
1. An electronic warfare defense system operable for:
receiving information from an incoming object detector, wherein the information comprises data regarding an incoming object;
processing the information received from the incoming object detector; and
sending a command for an antenna to emit a jamming signal capable of disrupting a SATNAV broadcast signal potentially received by the incoming object.
2. The defense system of claim 1 , wherein the incoming object detector comprises a battlefield radar.
3. The defense system of claim 1 , wherein the jamming signal comprises a directional signal.
4. The defense system of claim 1 , wherein the jamming signal comprises an omnidirectional signal.
5. The defense system of claim 1 , wherein the antenna comprises a parabolic antenna.
6. The defense system of claim 1 , wherein the defense system is operable for receiving user inputs, where in the inputs are used by the system to determine one or more modes of operation related to the emission of the jamming signal.
7. The defense system of claim 1 , wherein the jamming signal's characteristics are selected based upon the user inputs.
8. The defense system of claim 1 , wherein the jamming signal's frequency is selected based upon the information received from the incoming object detector.
9. The defense system of claim 1 , wherein the defense system is operable for receiving information from an identification system, and determining one or more modes of operation related to the emission of the jamming signal based on the information received from the identification system.
10. The defense system of claim 1 , wherein the defense system is operable for determining a mode of operation related to the emission of the jamming signal based on information it uses indicating the presence of friendly SATNAV-dependent devices.
11. The defense system of claim 1 , wherein the system is operable for transmitting and/or emitting a warning signal to comprising a warning that nearby friendly systems that a SATNAV jammer is active, and the type of jamming that may be conducted.
12. The defense system of claim 1 , wherein said incoming objects comprise one or more of a PGM, missile, rocket, vehicle, unmanned vehicle, water-based vehicle, and a torpedo.
13. The defense system of claim 1 , wherein the jamming signal is directed at the predicted location of an incoming object.
14. The defense system of claim 1 , wherein the jamming signal is directed at the actual location of an incoming object.
15. The defense system of claim 1 , wherein the antenna is physically controlled by actuators receiving a control signal from the defense system.
16. The defense system of claim 1 , wherein an alert is generated when the defense system has made a decision as to what type of response is required.
17. The defense system of claim 1 , wherein the antenna alternates its jamming signal output to frustrate jam-homing attacks.
18. The defense system of claim 1 , wherein a backup antenna is selected when the primary antenna is inoperable.
19. The defense system of claim 1 , wherein the jamming signal comprises a spoofing signal.
