Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle countermeasures, and in particular to an unmanned aerial vehicle satellite navigation deception device with directional and omnidirectional defense functions. Background Art

[0002] With the rapid development of drone technology, the application scope is getting wider and wider, and the threshold is getting lower and lower. In particular, the popular use of consumer-grade "low, slow and small" (referring to a flight altitude below 1,000 meters, a flight speed of less than 200 kilometers per hour, and a radar reflection area of ​​less than 2 square meters) drones has played a huge role in national economic construction, but it has also spawned a large number of "illegal flying" incidents, causing significant losses to national public security and people's lives and property. What's more, some criminals at home and abroad use drones to carry drugs, explosives and other contraband to violate laws and disciplines, penetrate defenses and attack sabotage activities, posing a serious threat to important targets and core areas. For this reason, it is urgent to take effective control measures against malicious or illegal drones, and the drone counter-industry came into being.

[0003] In the existing technology, usually due to the different algorithms and functional limitations of components, the same set of drones can only have one of the two functions of directional and omnidirectional in the navigation decoy device. Therefore, different equipment is required in different scenarios, and the cost of production, packaging, transportation, assembly, and personnel operation is high. Summary of the invention

[0008] Furthermore, the upper half of the turntable can rotate horizontally relative to the lower half of the turntable, so that when the host controls the directional transmitting antenna to transmit a decoy signal, the turntable drives the host to rotate.

[0009] Furthermore, the upper half of the turntable can rotate horizontally 360° relative to the lower half of the turntable.

[0010] Furthermore, the upper half of the turntable can rotate horizontally relative to the lower half of the turntable and is driven by a motor.

[0011] Furthermore, exposed horizontal axes are arranged on two opposite sides of the upper half of the turntable, and the exposed horizontal axes are driven by a motor to perform pitch rotation, thereby driving the main unit and the receiving antenna, omnidirectional transmitting antenna and directional transmitting antenna arranged on the top of the main unit to perform pitch rotation.

[0013] Furthermore, the support frame is retractable and foldable.

[0014] Furthermore, the receiving antenna, the omnidirectional transmitting antenna and the directional transmitting antenna are detachably installed on the top of the main unit.

[0015] The beneficial effects of the utility model are:

[0016] The drone satellite navigation decoy device with directional and omnidirectional defense functions provided by the utility model uses an omnidirectional transmitting antenna when protecting fixed scenes, such as areas with major safety hazards, key infrastructure, confidential places, military facilities, private territories, etc., and uses the defense circle function of the equipment to build a large hemispherical signal defense circle, which can drive away illegal drones that want to break into the protection range.

[0017] When protecting linear target areas such as borders, or when striking targets at longer distances, using directional transmitting antennas and turntables can output stronger power in a specified direction and accurately strike targets farther away in that direction.

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the following is a further detailed description of the drone satellite navigation deception device with directional and omnidirectional defense functions in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] like Figure 1 , Figure 2 , Figure 3 As shown, a UAV satellite navigation decoy device with directional and omnidirectional defense functions includes a host 1, a turntable 2, a support frame 3, and a receiving antenna 4. The turntable 2 is arranged on the top of the support frame 3, and the host 1 is detachably installed on the upper side of the turntable 2. The receiving antenna 4 is arranged on the top of the host 1. The omnidirectional transmitting antenna 5 and the directional transmitting antenna 6 are also arranged on the top of the host 1. The omnidirectional transmitting antenna 5 and the directional transmitting antenna 6 are switched on and off under the control of the host 1.

[0026] As a preferred implementation, the omnidirectional transmitting antenna 5 and the directional transmitting antenna 6 are switched on and off under the control of the host 1. The host controls the omnidirectional transmitting antenna 5 or the directional transmitting antenna 6 to transmit decoy signals, and quickly switches the signal defense form to achieve better defense effects in different application scenarios.

[0027] For example, the host 1 is used to control the target area as needed. When protecting a linear target area such as a border, or when striking a target at a longer distance, a directional transmitting antenna 6 can be used to output a stronger power in a specified direction and accurately strike a target at a longer distance in the direction.

[0028] For another example, when protecting a fixed area, such as a major safety hazard area, critical infrastructure, confidential places, military facilities, private territory, etc., an omnidirectional transmitting antenna 5 is used, and the defense circle function of the device is used to build a large hemispherical signal defense circle, which can drive away illegal drones that want to break into the protection range. The omnidirectional transmitting antenna has the characteristics of high gain, good low pitch angle gain, and directional pattern beam width. It also has a high and low temperature resistance, acid fog resistance, and UV protection cover, which provides protection for the antenna to work in the field for a long time.

[0031] Specifically, when using the directional transmitting antenna 6 to transmit a navigation decoy signal, the rotation function of the turntable 2 is enabled at the same time. The turntable 2 can drive the host 1 to rotate, and then drive the directional transmitting antenna 6 to rotate, so that the directional transmitting antenna 6 can be directed in a specified direction, so that the transmitted signal is concentrated in a fan-shaped range at a certain angle in that direction, and a stronger power is output to accurately strike targets farther away in that direction, thereby obtaining a better defense effect.

[0032] Furthermore, as a preferred implementation mode, when the host 1 controls the directional transmitting antenna 6 to transmit a decoy signal, the upper half of the turntable 2 can rotate horizontally 360° relative to the lower half of the turntable 2 .

[0033] As a preferred embodiment, the upper half of the turntable 2 can rotate horizontally relative to the lower half of the turntable 2 and is driven by a motor.

[0034] As a preferred embodiment, exposed horizontal axes are provided on two opposite sides of the upper half of the turntable 2, and the exposed horizontal axes are driven by a motor to perform pitch and rotation, thereby driving the main unit 1 and the receiving antenna 4, omnidirectional transmitting antenna 5 and directional transmitting antenna 6 arranged on the top of the main unit 1 to perform pitch and rotation.

[0035] Here, the focus is on driving the directional transmitting antenna 6 to perform pitch rotation.

[0036] As a preferred embodiment, the host 1 is detachably mounted on the upper side of the turntable 2 and is connected to the horizontal axes on two opposite sides of the upper half of the turntable 2 via a connecting bracket.

[0037] As a preferred embodiment, the support frame 3 is retractable and foldable.

[0038] As a preferred implementation manner, the receiving antenna 4 , the omnidirectional transmitting antenna 5 and the directional transmitting antenna 6 are detachably mounted on the top of the host 1 .
