Abstract

A vehicle system for detecting a jamming signal may include a receiver configured to receive a signal, the signal having signal properties. A controller may be in communication with the receiver configured to determine a jamming event probability based at least in part on the signal properties.

Claims

1. A vehicle system for detecting a jamming signal, comprising:

a receiver configured to receive a signal, the signal having signal properties; and

a controller in communication with the receiver configured to;

determine a jamming event probability based at least in part on the signal properties.

2. The system of claim 1, wherein the signal properties include at least one of a signal strength and a signal duration.

3. The system of claim 2, wherein the jamming event probability is based at least in part on comparing the signal strength and signal duration with a predefined threshold associated with each signal property.

4. The system of claim 3, wherein the jamming event probability is high in response to the signal strength and signal duration exceeding the predefined threshold.

5. The system of claim 3, wherein the jamming event probability is moderate in response to one of the signal strength and signal duration exceeding the predefined threshold.

6. The system of claim 1, further comprising a database in communication with the controller.

7. The system of claim 6, wherein the controller is further configured to provide an alert in response to the jamming event probability being one of moderate or high.

8. The system of claim 6, wherein the database is configured to maintain a pre-established jamming mitigation measure and wherein the controller is configured to activate the pre-established mitigation measure upon the recognition of the jamming event.

9. The system of claim 6, wherein the database is configured to maintain jamming event probability level data.

10. The system of claim 9, wherein the controller is configured to transmit the jamming event probability level data thereof.

11. A method comprising:

receiving, at a computing device, a signal from a receiver;

determining at least one of a strength and duration of the received signal;

comparing the at least one of the strength and duration of the received signal with a predefined threshold associated therewith; and

determining a jamming event probability based at least in part on the comparison of the strength and duration of the received signal with the respective predefined threshold.

12. The method of claim 11, wherein the jamming event probability is high in response to the strength and duration of the received signal exceeding the predefined threshold.

13. The method of claim 11, wherein the jamming event probability is moderate in response to one of the strength and duration of the received signal exceeding the predefined threshold.

14. The method of claim 11, further comprising sending an alert message in response to the jamming event probability being one of moderate or high.

15. The method of claim 11, further comprising activating a pre-established jamming mitigation measure.

16. The method of claim 11, further comprising maintaining jamming event probability level data recorded in response to the jamming event probability being one of moderate or high.

17. The method of claim 16, further comprising transmitting the jamming event probability level data to a remote server.

18. The method of claim 17, further comprising receiving a report from the remote server describing the jamming event probability level data.

19. A system for reporting a jamming event, comprising:

a database configured to maintain jamming event probability level data;

a computing device in communication with the database configured to analyze cumulatively maintained jamming event probability level data received from a location and generate a report; and

a communication device in communication with the computing device configured to send the report to a user.

20. The system of claim 19, wherein the computing device generates a location hot spot in response to the recurrence of jamming event probability level data transmitted from the location.
