1. Foreword
The drone
defense system has the functions of positioning detection, video tracking,
recognition, directional frequency interference suppression, and narrowband
precision strike against drones. The system achieves accurate detection,
tracking, positioning, and recognition of multiple low altitude drones through
radio lateral detection, radar positioning and tracking, optoelectronic
equipment tracking and ranging, and utilizes big data processing, artificial
intelligence, and machine learning. It uses drone navigation deception technology
to drive away drones, and uses electromagnetic suppression technology
(directional frequency interference and narrowband precision strike) to achieve
interference strikes against dangerous drone targets. Expand the traditional
planar security system to a three-dimensional security system, achieving low
altitude protection within a radius of 5000 meters of the defense area. It has
been widely applied in government agencies, prison guards, aviation airports,
petrochemical industry, military restricted areas, major events, and other
fields.
2. System

The low altitude drone defense
system consists of a backend control platform
(monitoring and controlling the entire process), a detection and tracking
system (for detection, recognition and alarm including a low
altitude detection radar, an optoelectronic tracking and ranging system,
Drone RF Detection and Localization device), precision strike device linked to
detection and tracking system, drone navigation
deception device (for directional displacement, no fly zone projection and

3. backend control platform
The control platform is a central
hub for the sharing and exchange of multi-sensor information and multiple
network nodes. Through distributed and multi center resource sharing services,
it realizes the interconnection, interworking, and data sharing of multi center
data resources and multiple nodes. It can store, manage, and analyze multiple
sensor data from multiple nodes in the region, and is the core of the system.
- Detection and warning: Drone intrusion detection and warning, which uses the front-end detector to detect signals and compare them in real-time with the back-end drone spectrum feature sample library model to determine the type, brand, and model of the invading drone. All day, all weather, unmanned, pre evaluated based on the level of hazardous events. It can simultaneously detect intrusion information from multiple drones, and provide multi-dimensional warning through voice and warning lights for illegal intrusion drones in the first time.
- Accurate positioning: The system utilizes multi-site front-end detection and sensing equipment, radar positioning technology, and optoelectronic tracking and ranging technology to fuse the signal positions of drones and remote controls with the detector's dimensional data. It can accurately locate the three-dimensional coordinate data of the invading drones and pilots, facilitating investigation and evidence collection of "black flying" personnel, and taking timely disposal measures
- Precise Defense: Designate to jam any one of the two drones;
- Traction drive off: Drone trajectory display, the system continuously tracks the three-dimensional coordinate data of the invading drone to form high-precision trajectory information. Determine the trend of the drone's flight trajectory, perform directional displacement of the drone, drive the drone away to a safe disposal area
- Full-autonomy Mode: 24-hour automatic detection and alarm, no need of personnel on duty
- Combined Defense: combination of narrowband, frequency hopping, low-power precise defense and wideband high-power jamming;
- Black & White List: Able to mark the drone into black and white list with a single click, and the white list drone does not alarm
- Model Library: Support all DJI models, mainstream brands, DIY drones. Cover more than 98% of drone models on the market
- Extended networking: The system adopts the principles of functional modularization and interface standardization design. It can be customized and expanded according to the different needs of the purchaser, or equipment configurations can be added or reduced according to the needs to meet the actual needs, expand system functions and performance.
4 low altitude
detection radar
This radar is mainly used in complex ground clutter
environments and various meteorological conditions. It undertakes the detection,
tracking, and classification recognition of "low, slow, and small"
targets 24/7, completing the detection and warning tasks of active targets in
key areas, providing information such as distance, azimuth, elevation, speed,
and attributes of the targets, and providing effective information support for
low altitude airspace monitoring and management.
Its main detection objects are "low slow small"
targets such as drones, light aircraft, helicopters, powered delta wings,
airships, floating balls, etc.

6 Drone RF
Detection and Localization device
This product is used for UAV detection, identification
and jamming system. has the advantages of easy deployment, mobile
compatibility, early warning and positioning with trajectory tracking. When a
drone enters defense area, this device can raise the alarm, determine the
real-time location of the target and the pilot through CRPC message-level
protocol cracking, and record the trajectory of the UAV
This product passively detects radio signals
in the defense area 24 hours a day without interruption through omnidirectional
antennas. after collecting wireless electrical signals, uses radio spectrum
sensing technology to extract UAV communication signals (mainly remote control
and image transmission signals) from background noise and conduct in-depth
reverse parsing of them.
Through offline analysis based on UAV
communication protocols to extraction of features (electronic fingerprint ID),
including but not limited to channel distribution, modulation scheme, coding
scheme, pilot sequence, synchronization sequence, link layer structure, etc.
Based on the above analysis results, a UAV detection database is formed, and
matching is detected in real time in the actual radio environment. If the
signal belongs to the whitelist, no warning and defense will be conducted. If
the signal is not on the whitelist, the system will automatically warn, and
transfer them to backend control platform, thus, achieving real-time detection
and recognition of drones within the surrounding airspace.
