With the increasing popularity of drone technology, the issue of low-altitude security has drawn more attention. And drone detection and positioning equipment has become the key force in ensuring low-altitude security. The handheld drone detection and positioning equipment, as a leader in this field, the core technology behind it is the key to achieving precise detection and positioning.
First, the key component in the handheld drone detection and positioning equipment - VCO
VCO (Voltage-Controlled Oscillator) is a fundamental component in the RF circuit, which can adjust the output signal frequency according to the change of input voltage, thereby enabling the capture of UAV signals in different frequency bands. In the handheld drone detection and positioning equipment, the overall RF front-end architecture centered on VCO can rapidly and accurately scan the wide frequency band of 100MHz to 6GHz, not missing any possible UAV signals, providing rich raw data for subsequent signal processing and analysis.
Secondly, in the signal detection and identification stage, the handheld drone detection and positioning equipment employs advanced spectrum detection technology.
Spectrum detection technology, by analyzing the electromagnetic spectrum in space, can identify the unique spectral characteristics emitted by different types of drones. For common models like DJI, since their signals have relatively fixed spectral patterns, handheld drone detection and positioning equipment can quickly match and identify them through the built-in database. For homemade drones such as those for flying through obstacles, or WiFi devices, their signals may be more complex and variable. However, handheld drone detection and positioning equipment, with their powerful signal processing capabilities, can extract the signal characteristics of these drones from the complex electromagnetic environment and accurately identify them. Especially in FPV detection, the equipment can capture and analyze the parameters of FPV live transmission signals (frequency points, bandwidth, protocol features), which rely on the precise capture and rapid decoding technology of the transmission signals of the drones. This enables security personnel to intuitively understand the flight status and field of vision of the drones, and further enhances the regulatory capabilities for these special drones.
Thirdly, precise positioning technology is another major core advantage of handheld drone detection and positioning equipment. It enables the precise positioning of both the unmanned aerial vehicle and the operator (remote control device).
In terms of drone positioning, the equipment calculates the precise position of the drone by receiving the video transmission signals and control signals sent by the drone, and presents it in the form of a "drone icon" on the electronic map interface. For DJI series drones that use the OcuSync video transmission method, the handheld detection and positioning equipment can further improve the positioning accuracy by leveraging the characteristics of this transmission technology. In terms of the pilot positioning, the equipment receives the control signals sent by the remote controller and uses advanced positioning algorithms to determine the position of the pilot, and displays it in the form of a "remote controller icon" on the electronic map. In addition, the equipment also has a pilot position navigation function, which can plan search routes based on the pilot's position and provide "one-click position navigation". The realization of this function requires combining positioning data with map navigation technology to ensure that security personnel can quickly and accurately locate the pilot's position.
Fourth, the unique identification technology is also an important component of the core technology of handheld drone detection and positioning equipment.
For the drones of the DJI series that use OcuSync, the equipment can recognize their unique identification marks. For the RID protocol drones, by analyzing their RID signals, the equipment can obtain the unique serial number (SN) and other identity information of the drones. For the WiFi drones, the SN code can also be extracted. The realization of this technology relies on in-depth research and analysis of the communication protocols of different types of drones. The equipment is equipped with multiple protocol parsing modules, which can quickly and accurately extract identity information from the drone signals, providing a key basis for the traceability and supervision of drones, and effectively preventing the anonymous flight and malicious operation of illegal drones.
Fifth, in the field of multi-target monitoring and trajectory tracking technology, the handheld drone detection and positioning equipment has demonstrated remarkable capabilities.
Under certain circumstances, the equipment is capable of simultaneously detecting ≥10 unmanned aircraft. This requires efficient signal processing and data handling capabilities, enabling parallel processing of multiple drone signals to avoid interference and confusion among them. In terms of trajectory tracking, the equipment continuously receives the position signals of the drones, records and stores them, and then displays the flight trajectories of the drones on the electronic map interface in real time. At the same time, the equipment also supports the function of historical trajectory playback, which requires reliable data storage technology and efficient data retrieval technology to ensure the complete preservation and quick retrieval of historical flight data, so that security personnel can analyze the flight paths of the drones and identify potential safety hazards and patterns.
Sixth, in addition, the system operating environment and hardware configuration of the handheld drone detection and positioning equipment also provide strong support for the implementation of core technologies.
The equipment adopts the Android 12 operating system, which has excellent stability and compatibility, providing a smooth platform for the operation of various applications and algorithms. The configuration of 8GB memory and 256GB storage ensures that the device can quickly process a large amount of signal data and run complex algorithms, while also being able to store a large amount of detection records and historical data. The 6-inch large touch screen has a high resolution of 2160*1080 pixels, providing users with a clear operation interface and data display interface, facilitating real-time viewing of various information of the unmanned aerial vehicle and operating the equipment.
