Anti-drone manufacturer jammer module producer

With the rapid development of drone technology, its wide application in fields such as aerial photography, logistics and agriculture has brought convenience, but it has also triggered challenges such as illegal intrusion, privacy violation and security threats. For instance, in 2024, a certain international airport suffered flight delays due to drones illegally entering no-fly zones, resulting in economic losses amounting to several million dollars. This highlighted the urgent need for drone control. As a portable and efficient anti-drone tool, the drone anti-gun interferes with the communication and navigation systems of drones by emitting high-power radio frequency signals, forcing them to land or return. It has become an important equipment for maintaining public safety and privacy protection. This article will provide a detailed introduction to the working principle and application value of the drone countermeasure gun from four aspects: core technology composition, interference mechanism, practical application scenarios, and future development trends, revealing how it provides precise support for security protection in dynamic environments.

一、 Core Technologies of Anti-Drone Guns

The drone anti-gun is a portable anti-drone device that integrates multiple advanced technologies, including a radio frequency interference module, a directional antenna system, a signal generation and control unit, as well as a power supply and heat dissipation system. These technologies work together to ensure that the countermeasure gun can quickly and accurately suppress the drone signals.

Rf interference module: The core driving force for signal suppression

The radio frequency interference module is the core component of the countermeasure gun, responsible for generating and amplifying high-power radio frequency signals to suppress the communication and navigation functions of unmanned aerial vehicles. The module usually covers the common frequency bands of unmanned aerial vehicles, including 2.4GHz, 5.8GHz(Wi-Fi communication) and 1.5GHz(GPS L1 navigation), with an output power range of 10W-50W and an interference distance of up to 500 meters to 2 kilometers. The module adopts solid-state power amplifiers (such as those based on GaN or LDMOS technology), featuring high efficiency (power-added efficiency PAE of over 45%) and broadband characteristics, capable of simultaneously interfering with multiple frequency bands. The amplifier is equipped with a bandpass filter to remove out-of-band noise and ensure signal purity. For example, the radio frequency module of a certain type of countermeasure gun can output 20W of power in the 2.4GHz frequency band to suppress the remote control signal of the DJI Mavic series of unmanned aerial vehicles. In addition, the module supports dynamic power regulation, adjusting the output intensity according to the distance of the unmanned aerial vehicle to optimize energy efficiency.

Directional antenna system: The guarantee of precise signal projection

The directional antenna system is responsible for concentrating and projecting interference signals towards the direction of the target unmanned aerial vehicle (UAV), enhancing interference efficiency and reducing false interference to surrounding equipment. Commonly used antenna types include Yagi antennas and parabolic antennas, with a gain range of 10-15dB, a beam width of approximately 30-60°, and support for precise interference ranging from 500 to 2000 meters. Some high-end countermeasure guns adopt phased array antennas and achieve dynamic beam adjustment through electronic scanning to track moving unmanned aerial vehicles. The antenna is made of lightweight materials (such as carbon fiber or high-strength plastic), with a weight controlled between 0.5 and 1 kilogram, making it convenient for handheld operation. The system is also equipped with an optical sight or laser pointer to help the operator quickly lock onto the target. For instance, a certain countermeasure gun can precisely aim at a drone from 50 meters away through an infrared sight, enhancing the success rate of interference. The antenna system supports quick disassembly and assembly to meet the requirements of different tasks.

Signal generation and control unit: Intelligent signal management

The signal generation and control unit is responsible for generating interference waveforms and coordinating equipment operation, and is usually based on a digital signal processor (DSP) or a Field Programmable gate array (FPGA). The unit generates multiple interference signals, including white noise (covering the entire frequency band), sweep signals (for frequency-hopping drones), and pseudo-signals (for GPS spoofing). For instance, white noise can reduce the signal-to-noise ratio of drones to below -10dB and cut off the remote control signal. False signals can induce unmanned aerial vehicles to fly to the wrong coordinates. The control unit supports spectrum analysis function, which can detect the communication frequency of the unmanned aerial vehicle (such as 2.437GHz) in real time and dynamically adjust the interference signal, with a response time of less than 100 milliseconds. Some countermeasure guns integrate software-defined radio (SDR) technology and support new frequency bands (such as 433MHz or 6GHz Wi-Fi) through firmware upgrades. The unit is equipped with a simple operation interface, such as an LCD display or buttons, which show the target frequency and battery status, facilitating single-person operation.

Power supply and cooling system: Support for portability and stability

The power supply system provides stable power for the countermeasure gun, typically using high-capacity lithium batteries (such as 11.1V, 5000mAh), supporting continuous operation for 1-2 hours. It is equipped with fast charging and hot-swappable functions, making it suitable for field missions. The heat dissipation system controls the heat generated by the high-power RF amplifier through aluminum alloy heat sinks and micro fans. For instance, after 30 minutes of operation, the internal temperature of a certain model of countermeasure gun can reach 60℃. The cooling system keeps it below 45℃ to ensure stable performance. The system adopts a lightweight design, with a total weight controlled between 2 and 5 kilograms. It is equipped with an ergonomic handle and shoulder strap to enhance portability. Some models also support an external power interface, which can be connected to the vehicle power supply to extend the operating time and is suitable for long-term tasks.

  Through the coordinated operation of the RF interference module, directional antenna system, signal generation and control unit, as well as the power supply and heat dissipation system, the unmanned aerial vehicle (UAV) countermeasure gun achieves portable and efficient signal suppression capabilities, providing a technical foundation for responding to UAV threats in dynamic scenarios.
