According to the characteristics of the airport, the construction opinions of relevant projects and the overall work requirements of UAV prevention and control and Bird Monitoring in the aviation control area, 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 management and control, so as to meet the requirements of multi-point control Perception, identification, disposal and notification requirements of low altitude small aircraft in multi station networking mode. Finally, a UAV control platform for the airport industry is built.
The low altitude airspace management and control integration 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.

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;
● 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 of rapid damage and precision attack on UAVs, as well as the ability of medium-sized anti 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 to fully grasp the air situation;
● truly unattended, from automatic target discovery, alarm, tracking, locking to automatic strike, the whole process is implemented automatically without human intervention;
● 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.
