According to the characteristics of border defense, the construction opinions of relevant projects and the overall work requirements of UAV prevention and control in border defense areas, this scheme constructs an anti UAV three-dimensional security system, and realizes the detection, tracking, rejection, display and control of low altitude small aircraft in key areas and the interconnection within the prevention and control system by establishing an integrated platform for low altitude airspace control, so as to meet the perception and control of low altitude small aircraft under the mode of multi-point control and multi station networking Identification, disposal and notification requirements. Finally, a customs border UAV control platform is built.
The low altitude airspace management and control - integrated platform includes five modules: detection module, photoelectric module, reaction module, unified communication module and system brain command center module. Each module is supported by different types and quantities of hardware equipment and system software. The overall composition is shown in the figure below.
Border control should not only control UAVs from the air, but also control the smuggling and intrusion of ground personnel. According to China's border emergency needs, the platform can be connected to ground radar and boundary vibration system, and can link photoelectric, so as to achieve the tracking and linkage between ground radar and photoelectric. At night, the patrol inspection and arrest of border guards can be realized by cooperating with high illumination searchlights.

系统功能system function
● wide range and high-precision detection. The measured detection distance of Dajiang series UAV exceeds 10km, and the detection error within 3km does not exceed 10m; Using improved radio detection equipment and advanced wireless propagation model, the passive detection distance is greater than 5km, and the detection azimuth error of multiple stations (more than three stations) is less than 1 °;
● very low false alarm rate and stable and continuous target track, which can distinguish UAV and bird, identify hovering UAV and realize flying hand positioning;
● radar equipment and photoelectric tracking equipment can not only track and identify UAVs in the air, but also select ground radar to cooperate with photoelectric to monitor ground vehicles and personnel to prevent smuggling.
● multi target detection capability, which can process 800 batches of targets and track 70 batches of targets at the same time;
● high precision infrared optical tracking capability. Under ordinary meteorological conditions, the target's stable tracking distance exceeds 3km during the day and 2km at night;
● diversified attack means, which can implement communication interference and navigation deception against UAVs at any frequency point in 400mhz-6ghz frequency band, directional or omnidirectional interference, and drive off and forced landing;
● it can be integrated with strong microwave weapons and high-power laser weapons, and has the ability to quickly damage and accurately strike UAVs, as well as the ability of medium-sized anti bee swarm UAVs;
● strong command and control capability, including friend or foe identification, intention determination and threat assessment, equipped with high-precision GIS service and multi-level early warning mechanism, and fully grasp the air situation;
● truly unattended, from automatic target discovery, alarm, tracking, locking to automatic strike, the whole process is automatically implemented No human intervention is required;
● a wide range of products, including fixed deployment, on-board system, modular movable and other product forms, to customize professional solutions for users;
● independent research and development of software and hardware equipment, independent intellectual property rights and high cost performance.
