Background

With the rapid evolution of unmanned aerial vehicle (UAV) technology, the demand for UAV applications has increased significantly. Small commercial multi-rotor drones have become popular consumer products due to their compact size, low noise, portability, and ease of operation. As the global UAV market continues to expand, an increasing number of UAV enthusiasts now own personal drones, bringing with them a growing number of safety concerns.

While UAVs provide convenience for aerial photography and payload operations, they also pose serious risks to public safety and law enforcement. Incidents involving invasion of privacy, illegal cargo transportation, the display of extremist banners, cross-border smuggling, and other unlawful activities using drones have raised widespread concern worldwide.

In many sensitive areas, UAV flight is strictly prohibited. UAV monitoring and countermeasure systems are therefore widely required in airport airspace, nuclear power facilities, military control zones, prisons, satellite launch sites, strategic infrastructure projects, government institutions, as well as confidential areas, including national security agencies, major events, archaeological sites, and locations involving sensitive commercial information. UAV-based criminal activities such as drug trafficking, smuggling, illegal transportation, and cross-border sabotage further highlight the urgency of effective UAV control.

Although flight regulations and regulatory authorities have been established in many countries, incidents involving unauthorized UAV intrusions into government offices, airport flight paths, landmark buildings, and military bases continue to occur.

Limitations of Existing UAV Monitoring Technologies

Current UAV monitoring technologies mainly include:

Radar Technology
Military radar systems are used to detect and locate civilian UAVs through Doppler or phased-array radar. However, low-altitude, small, slow, or hovering UAVs have small radar cross-sections and are difficult to detect, especially at close range. Continuous operation also results in high operational costs.

Electro-Optical Technology
Visible light and infrared imaging systems combined with laser ranging can track UAVs. However, optical systems alone cannot provide wide-area monitoring and must rely on additional electronic detection methods to provide directional guidance.

Radio Frequency (RF) Monitoring Technology
Traditional RF monitoring relies heavily on manual identification of UAV control and video transmission signals. Existing solutions suffer from multiple limitations, including:

• Inability to determine UAV elevation angles

• Difficulty identifying rapidly changing flight directions

• Inability to detect and locate multiple UAVs simultaneously

• Limited discrimination between Wi-Fi and UAV video signals at close range

• Short detection range (typically around 1 km)

• Inability to automatically identify UAV models

• High cost with low detection efficiency

These deficiencies demonstrate the need for improved UAV countermeasure solutions.

Invention Overview

To address the above challenges, this utility model provides a counter-UAV system and command & control vehicle that passively and automatically detects UAV signals, identifies UAV and remote controller models, generates visual and audible alarms, stores alarm records, records detection data in real time, and notifies other security systems via interfaces. Based on detection results, the countermeasure system automatically performs directional countermeasures to ensure low-altitude airspace security.
