Abstract

The disclosure relates to a classification system which includes a classification circuit which may determine a classification of a signal based on comparing signal data received via a sensor to data in a database. The classification circuit may determine an interface protocol based on the classification.

Claims

1. A classification module comprising:

a classification circuit configured to determine a classification of an RF signal based on comparing signal data received via a sensor to data in a database, wherein the classification circuit uses statistical features associated with the RF signal to determine the classification, wherein the signal data is provided using spectral analysis for determining modulation type, center frequency, and bandwidth without using demodulating signal recognition;

the classification circuit being configured to determine an interface protocol based on the classification.

2. The classification module of claim 1, wherein the statistical features are clustered and the classification circuit uses cluster data to determine the classification.

3. The classification module of claim 1, wherein the classification circuit being further configured to generate a new classification identification in the database based on a determination that the signal data is not within the database.

4. The classification module of claim 1, wherein the classification circuit being further configured to determine that a signal source represents a threat.

5. The classification module of claim 4, wherein the classification circuit being further configured to generate a message relating to the threat, transmit the message to an outside source, and transmit a jamming signal via a jamming engine.

18. The classification module of claim 1, wherein the classification circuit comprises at least one of a statistical Gaussian mixture model and Bayesian mixture model for classifying a signal.

6. A method of communicating, comprising:

receiving signal data, the signal data being statistical measures associated with the spectrum of an RF signal, wherein the signal data is provided using spectral analysis for determining modulation type, center frequency, and bandwidth without using demodulating signal recognition;

comparing the signal data to data in a database;

determining a classification of the RF signal based on a comparison of the signal data to the data in the database; and

determining an interface protocol based on the classification.

7. The method of claim 6, further comprising communicating between a first communication device and a second communication device utilizing the interface protocol.

8. The method of claim 6, further comprising generating a new classification identification in the database based on a determination that the signal data is not within the database.

9. The method of claim 6, further comprising determining that a signal source represents a threat based on the signal data.

10. The method of claim 9, further comprising generating a message relating to the threat and transmitting a jamming signal to the signal source.

11. The method of claim 6, further comprising:

receiving a second signal data;

comparing the second signal data to data in a database;

determining a second classification of a second signal based on a comparison of the second signal data to data in the database; and

determining a second interface protocol based on the second classification.

12. The method of claim 11, further comprising communicating between a first communication device, a second communication device, and a third communication device utilizing the first interface protocol and the second interface protocol.

19. The method of claim 6 wherein target waveforms may be triggered on a multi-channel Software Define Radio, the target waveforms also being able to be triggered on different channels of the same Software Define Radio or a separate Software Define Radio.

20. The method claim 6 further comprising receiving a waveform that does not match any known waveform, utilizing band shifting to map the wave form to find a signal pattern resulting in a shifted waveform, and assigning the waveform to an existing class identification based on the shifted waveform.

13. A classification module comprising:

an input for receiving signal data, the signal data comprising cluster data; and

an electrical processor for comparing the signal data to data in a database,

the electrical processor determining a classification of a signal based on a comparison of the cluster data to the data in the database, the cluster data being in a window, wherein the signal data is provided using spectral analysis for determining modulation type, center frequency, and bandwidth without using demodulating signal recognition, the electrical processor also

determining an interface protocol based on the classification.

14. The classification module of claim 13, wherein the electrical processor communicates between a first communication device and a second communication device utilizing the interface protocol.

15. The classification module of claim 13, wherein the electrical processor generates a new classification identification in the database based on a determination that the signal data is not within the database.
