Abstract
Description
Technical Field
[0001] This utility model relates to the field of drone countermeasures technology, specifically a lightweight drone countermeasures device. Background Technology
[0002] With the rapid development of drone technology, the problem of drone misuse is becoming increasingly serious, especially in security-sensitive areas such as airports, offices, and other important locations. Traditional countermeasures against drones include radio jamming and cyberattacks.
[0003] In existing technologies, fixed countermeasures equipment is heavy and bulky, and its full-band high-power design results in power redundancy, which cannot meet the needs of mobile deployment. Portable countermeasures equipment is extremely heavy and has a slow response speed, making it difficult to track targets in real time. Both are caught in a triple constraint dilemma of "form-function-weight". Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a lightweight UAV countermeasure device, which solves the problems of existing technologies, such as the large weight and size of fixed countermeasure devices, the power redundancy caused by the full-band high-power design, which cannot meet the needs of mobile deployment; and the excessive weight and slow response speed of portable countermeasure devices, which make it difficult to track targets in real time. All of these are trapped in the triple constraint dilemma of "form-function-weight".
[0005] This utility model provides the following technical solution: a lightweight UAV countermeasure device, including an antenna radome, wherein an antenna unit and a power amplifier unit are disposed inside the antenna radome; The antenna unit includes a substrate on which four single-polarization directional antennas are disposed; The power amplifier unit includes a control housing, on which a power amplifier module, an electrical control module, and a power supply module are disposed. The control housing is also provided with heat dissipation fins and a cooling fan. The power amplifier module, the electrical control module, and the power supply module are all connected to the substrate via radio frequency lines.
[0006] Preferred technical solution 1: The radome is provided with a curved shape, and the interior of the radome is provided with longitudinal and transverse reinforcing ribs.
[0007] Preferred technical solution 2: The antenna cover is provided with multiple mounting posts inside, each mounting post having a threaded hole, and the substrate having multiple connection holes that match the mounting posts.
[0008] Preferred technical solution 3: Two connecting rods are fixedly installed on the substrate, and each connecting rod is provided with a mounting flange.
[0009] Preferred technical solution four: The four corners where the substrate connects to the antenna cover are provided with a stop design, and the stop designs interlock with each other.
[0010] Preferred technical solution five: A through mounting bolt hole of specification M is provided between the substrate and the control housing.
[0011] Compared with existing technologies, this utility model provides a lightweight UAV countermeasure device with the following advantages: During operation, an external power supply is first connected through the power supply module in the power amplifier unit to power the antenna unit, power amplifier module, electrical control module, and cooling fan. The electrical control module receives external commands, identifies parameters such as the target UAV's frequency band and location, selects the core frequency point, and sends commands to the power amplifier module. The power amplifier module amplifies the countermeasure signal of the target frequency band and transmits it directly to the antenna unit's substrate via radio frequency lines. The four single-polarization directional antennas integrated on the substrate activate the corresponding frequency band channels. The radome transmits countermeasure signals to the target. The radome features a curved design with internal longitudinal and transverse reinforcing ribs to counteract the solidification deformation of non-metallic materials. The base plate and radome interlock via four corner stop designs, and multiple mounting posts inside the radome mate with the connection holes on the base plate, secured with bolts to ensure stable signal transmission. Two connecting rods and mounting flanges on the base plate connect the device to the mounting platform. If mounted on a drone or vehicle, high gain or a fan-shaped array can be used to expand the coverage area. Heat dissipation fins and fans on the control housing work together to dissipate heat. The base plate and control housing are secured with M-type through-hole mounting bolts, ensuring stable operation even during vibrations, thus effectively countering target drones. This device is lightweight, can be mounted on multiple platforms, has a stable structure, is resistant to deformation, has a fast response, wide coverage, low power consumption, and is easy to assemble and disassemble, breaking through the constraints of traditional device form, function, and weight.

The base plate 4 and the radome 1 interlock via four corner stop designs, and multiple mounting posts 9 inside the radome 1 mate with the connection holes of the base plate 4, secured with bolts to ensure stable signal transmission. Two connecting rods 10 and mounting flanges on the base plate 4 connect the device to the mounting platform. If mounted on a drone or vehicle, it can utilize high gain or form a fan-shaped array to expand the coverage area. The heat dissipation fins 6 and cooling fan 7 on the control housing 5 work together to dissipate heat. The base plate 4 and the control housing 5 are secured with M4 through mounting bolt holes to ensure stable operation of the device during bumpy rides, thus effectively countering target drones. This device is lightweight, can be mounted on multiple platforms, has a stable structure, is resistant to deformation, has a fast response, wide coverage, low power consumption, and is easy to assemble and disassemble, breaking through the constraints of traditional device form, function, and weight.
