1. Proposal Description

Unauthorized UAV intrusions create new-emerging security risks for critical public-sector facilities. Illegal drones are capable of threatening energy infrastructure, port facilities and other key public assets. Their high-speed maneuverability and low-altitude flight profiles bring practical challenges to conventional airspace monitoring systems.

Meanwhile, existing detection solutions perform poorly against low-altitude, low-speed and small-size targets. Ground clutter and interference sources such as birds often lead to high false-alarm rates. RF detection relies on signal emission from targets and may fail against pre-programmed autonomous flight. When facing frequency-hopping communication links, countermeasure equipment requires real-time signal analysis and dynamic parameter adjustment, while many existing systems still depend on preset modes and manual triggering.

To solve these challenges, our company presents this integrated counter-UAS system. It is specially optimized for high-speed maneuvering UAVs with low radar cross-section and frequency-hopping links. The solution fills monitoring gaps for key-site medium-and-low altitude airspace and mitigates risks from large-scale multi-UAV unauthorized intrusions.

2. System Advantage

The system adopts multi-source detection and layered countermeasure technologies. It combines low-altitude radar monitoring, RF reconnaissance and direction-finding with counter-measure hardware for gap-filling coverage of key sites and multi-intruder response. Portable reconnaissance, response and signal-deception devices support on-site mobile deployment.

The command-control platform fuses radar and RF detection data, automatically recommends response strategies and conducts unified equipment scheduling. Multi-device TDOA networking improves detection performance for low-observable targets. Functional modules can be tailored for different projects, and the whole system supports full operation auditing.

3. System Description

The complete system consists of low-altitude radar detection equipment, RF detection equipment, RF interference equipment and command & control platform.

Low-altitude radar equipment, RF detection equipment and UAV counter-measure devices constitute fixed-type and vehicle-mounted counter-UAS subsystems. They are designed for detection and signal counter-measures against high-speed maneuvering UAVs within medium-and-low altitude airspace, applicable for air-monitoring gap-filling at key sites and multi-intruder security response.

The command & control platform aggregates multi-source detection data to realize target correlation analysis, threat level assessment and unified scheduling of response resources. It supports standalone operation for single device as well as networked multi-device collaboration, improving regional air-situation awareness and overall security-response efficiency.

3.1 Low-Altitude Detection Radar

                                        Table 1 Low-Altitude Detection Radar Specifications

The Low-Altitude Detection Radar is designed following principles of low-cost, low-power consumption, reliable sealing performance and electromagnetic compatibility. It delivers stable detection and accurate measurement with advanced technical architecture. AI-enabled intelligent identification effectively suppresses false alarms.

Open system architecture features front-end and back-end decoupling and supports online firmware upgrade. This radar searches and tracks multiple low-altitude targets within the protected zone with 24/7 all-weather unattended operation. It classifies and identifies targets including drones and birds and maintains stable detection performance under heavy clutter environment. Vehicle-mounted mobile deployment is supported. Built-in functions cover system self-test, fault detection and fault location.

3.2 RF Detection Device

This unit integrates phase interferometer direction-finding, amplitude-correlation algorithm and Cognitive Radio Protocol Cracking (CRPC) technology. Combined with high-gain wide-coverage reconnaissance antennas and CRPC capability, it achieves UAV signal reconnaissance, direction-finding and model identification, outputting target data for early warning, surveillance and tracking within protected airspace.

3.3 RF Interference Device

Multi-channel link-jamming technology is adopted. By transmitting customized jamming waveforms, UAV remote-control and video-transmission links can be suppressed. Spoofing satellite navigation signals received by drones enables response effects including expulsion, forced landing and virtual no-fly-zone enforcement, delivering effective protection within system coverage.

3.4 Portable Detection and Countermeasure Device

                                                      Table 4 Portable Detection and Countermeasure Device Specifications

This integrated device combines reconnaissance, identification and counter-measure functions to deliver efficient detect-and-respond capability. Through RF spectrum scanning and real-time signal feature decoding, it captures remote-control and video-downlink signals from unauthorized UAVs. Electromagnetic-interference capability disrupts drone remote-control, video transmission and navigation signals. Navigation spoofing function supports active expulsion of intruding UAV targets.

3.5 Handheld Drone Detection Equipment

Through deep signal analysis and feature recognition, the handheld UAV detector can detect consumer-grade drones, FPV racing drones and typical industrial UAVs within effective range. It also identifies suspected signals from unknown UAV models, triggering timely vibration and audio alerts.

3.6 Command and Control Platform

Visual operational map interface fuses and displays all target information on GIS map. Once UAV intruders are detected, early-warning will be activated automatically. Threat assessment is performed according to pre-configured electronic-fence rules and threat classification.

The platform supports one-click or auto-driven command dispatch of properly-positioned counter-measure units, and feeds back real-time response results on user interface. It integrates full-domain air-situation awareness, intelligent security-decision support and response-effect evaluation, built for intensive low-altitude security-protection scenarios.
