Description

Technical Field

[0001] This invention relates to the field of radio countermeasures and broadcasting technology, and in particular to a method, device and storage medium for countering unmanned aerial vehicles (UAVs) based on countermeasures equipment. Background Technology

[0002] Broadcasting countermeasures information refers to the process by which countermeasures equipment sends its own identification information to receiving equipment within the airspace, and provides relevant control information to the receiving equipment. The core objective of broadcasting countermeasures information is to resolve data interoperability, collaborative decision-making, and status sharing between systems, in order to build a unified, real-time, and intelligent low-altitude defense network against unmanned aerial vehicles (UAVs).

[0003] However, current countermeasures against target drones often lack the ability to broadcast information about the countermeasures to the target drone and its surrounding airspace. This means that both the countermeasures and the broadcasting of countermeasure information must occur at different times and frequencies. Consequently, the efficiency of both broadcasting countermeasure information and countermeasures against target drones is low, resulting in inefficient drone control. Furthermore, failing to broadcast countermeasure information to the target drone and its surrounding airspace during countermeasures renders the countermeasures unidentifiable, lacking transparency and making it difficult to assign blame when problems arise.
