Abstract

A portable countermeasure device is provided comprising one or more directional antennae, one or more disruption components and at least one activator. The portable countermeasure device further comprises a body, with the directional antennae are affixed to a front portion of the body. The one or more disruption components may be externally or internally mounted to the device body. The portable countermeasure device is aimed at a specific drone, the activator is engaged, and disruptive signals are directed toward the drone, disrupting the control, navigation, and other signals to and from the drone.

Claims

1. A portable countermeasure device, comprising:

at least one directional antenna;

at least one signal disruption component in electronic communication with the at least one directional antenna;

at least one activator communicatively coupled to the at least one signal disruption component; and

a firearm form factor body having a top portion, a bottom portion, a first side, a second side, a front, and a back, wherein the at least one signal disruption component is disposed therein.

2. The portable countermeasure device of claim 1, wherein the at least one signal disruption component further comprises:

at least one signal generator; and

at least one amplifier coupled to the at least one signal generator, wherein the at least one signal generator is configured to generate a disruptive signal on an associated frequency band and the corresponding at least one amplifier amplifies the generated disruptive signal.

3. The portable countermeasure device of claim 2, wherein the at least one directional antenna is selected from the group consisting of a helical antenna, a Yagi antenna, a cylindrical antenna, or a parabolic antenna.

4. The portable countermeasure device of claim 3, wherein the at least one directional antenna is removably attached to the body, the at least one directional antenna extending outward therefrom.

5. The portable countermeasure device of claim 4, further comprising a power source selected from the group comprising a battery pack or an external power supply.

6. The portable countermeasure device of claim 5, wherein the body is a firearm form factor body, further comprising a battery well configured to receive a removable battery pack, the removable battery pack supplying power to the at least one jamming component.

7. The portable countermeasure device of claim 6, further comprising at least one sight, the at least one sight removably coupled to the top portion of the body.

8. The portable countermeasure device of claim 7, further comprising a selector control, the selector control in communication with the at least one signal disruption component and operable to select one or more frequency bands in which a signal is generated.

9. The portable countermeasure device of claim 8, wherein the at least one disruption component generates disruption signals on GPS, control and/or Wi-Fi frequencies.

10. The portable countermeasure device of claim 9, wherein disruption signals include at least one of noise, spoofing, or alternate control commands.

11. The portable countermeasure device of claim 9, wherein the at least one directional antenna is configured to transmit each generated disruption signal simultaneously at a drone.

12. A portable countermeasure device, comprising:

at least one of a removable power supply or an external power supply;

a firearm form factor body having a top portion and a bottom portion;

at least one disruption component disposed within the body and in communication with the at least one removable or external power supply, and configured to generate at least one disruption signal on at least one associated frequency bands;

at least one activator coupled to the body and in operable communication with the at least one removable or external power supply and the disruption components; and

at least one directional antenna in communication with the at least one disruption component, the at least one directional antenna removably attached to the body and configured to emit the at least one disruption signal generated by the at least one disruption component.

13. The portable countermeasure device of claim 12, wherein the at least one disruption component further comprises at least one signal generator and at least one corresponding amplifier, the at least one signal generator and corresponding at least one amplifier being operatively coupled to the at least one removable or external power supply and configured to generate the at least one disruption signal on the at least one frequency band.

14. The portable countermeasure device of claim 13, wherein the body further comprises a battery well located adjacent the at least one activator on the bottom portion of the body, the battery well configured to receive a removable battery pack supplying power to the at least one disruption component.

15. The portable countermeasure device of claim 14, further comprising at least one sight affixed to a top portion of the body.

16. The portable countermeasure device of claim 14, wherein the at least one frequency band corresponds to navigation, control, Wi-Fi, GPS, and Bluetooth frequency bands.

17. The portable countermeasure device of claim 16, further comprising a selector control on a first side of the body, the selector control operable to control activation of the at least one disruption component responsive to an activation of the activator.

18. The portable countermeasure device of claim 12, wherein the at least one disruption signal comprises at least one of a noise signal, a spoofing signal, or alternate control command signal.
