In order to promote the development of the low-altitude airspace economy, my country has gradually promoted the pilot reform of low-altitude airspace management since 2009. Low-altitude airspace has been opened in an orderly manner since 2020. During this period, the number of drones has increased exponentially. At the same time, the number of drones has increased exponentially. The problem of "black flying" has also become increasingly prominent. Incidents such as drone interference, smuggling, and even terrorist attacks occur frequently around the world, seriously affecting social public security and people's normal production and living order. Due to the characteristics of "low, slow and small" drones, this greatly increases the difficulty of drone control. The core technical problem lies in effective early warning, positioning, tracking and countermeasures. At present, traditional countermeasures such as radio direction finding and radar are unable to fully respond to the security threats posed by "black flying" UAVs. Low-altitude control remains a major problem faced by both military and civilian parties. Research on UAV countermeasures and equipment is in Applications in low-altitude airspace management are imminent.
一、 Characteristics of UAVs and difficulties in countermeasures
1. The fuselage is small in size and the materials tend to be non-metallic. With the development of composite and stealth technology materials, it becomes more difficult to detect, identify and warn.
二、Development status of domestic UAV countermeasures equipment
四、The development trend of UAV countermeasures technology in low-altitude airspace management
According to the plan of the National Air Traffic Control Commission, the low-altitude airspace management reform pilot provinces have established a low-altitude airspace collaborative operation center to gradually build China's air traffic supervision system. In view of this requirement, strengthening low-altitude control mainly focuses on the seven links of "examination, investigation, supervision, control, harassment, destruction, and punishment". From a broad perspective, it is management and control. Management is mainly reflected in laws and regulations. For the management of "low, slow and small" drones, the main emphasis is on "management" to achieve "airspace limitation, equipment registration, licensed operation, and effective monitoring." The main emphasis of control is to use technical means to distinguish black and white lists and a series of security measures such as detection, perception, avoidance, denial, and evidence collection.
