1.  Overview

Due to their diverse functions and high cost-effectiveness, drones have seen a sharp increase in applications in both military and civilian fields in recent years. The changes in military strategies and tactics caused by the mixed use of military and civilian drones have attracted widespread attention from military forces around the world. With the continuous reduction of production costs, drones have become more accessible to different actors. The technical capabilities of drones have been maliciously or illegally used in civilian fields. These maliciously used drones may be modified versions of commercial models or models intentionally designed for illegal purposes. Some potential malicious activities involving these drones include surveillance and privacy violations, security threats, harassment and sabotage, transportation of illegal and harmful items, and weapons.

In the civilian field, the development of unmanned aerial vehicles has promoted the development of low-altitude economy. At the same time, it has also brought new problems. In recent years, accidents caused by illegal drone flights have been frequent. Criminals use drones for peeping, illegal shooting of major events, illegal manipulation of drones to damage infrastructure, such as high-voltage power lines causing regional power outages, forcing light rail trains to stop, interfering with aviation order, and even using drones to transport drugs and smuggle across borders, which seriously threaten social public safety.

In the military field, with the gradual large-scale application of drones in military operations, the development of anti-drone equipment has become a necessary path to win modern unmanned wars. In the context of current great-power competition and game, the probability of local conflicts is increasing, which also leads to complex forms, appearances, and combat modes of modern wars. Unmanned aerial vehicles, which are easy to deploy, simple to use, and have high operational cost-effectiveness, are used more and more frequently in terrorist attacks, armed conflicts, and other fields. The US Army lists drones as one of the "five major threat platforms" (fixed-wing aircraft, drones, ballistic missiles, cruise missiles, and helicopters), and considers drones to be one of the most destructive air threats, believing that drones will pose a threat to the entire combat process.

Curbing the potential threats posed by unmanned aerial vehicles has become an urgent problem to be solved.

The system uses cognitive radio protocol cracking technology, applying advanced radio reverse engineering and security analysis to drone detection and defense, achieving "three noes and two accuracies": passive detection, unattended operation, 360° no dead angles, precise strikes, and accurate direction finding. The main targets are low-flying conventional drones, FPV drones, and other air targets.

Taking the airspace of activity sites as the core protection area against drone invasion, it forms a drone detection and defense system capable of identification, early warning, positioning, interference, and countermeasures, achieving full-domain detection, early warning, interference, and countermeasures against illegal drones.

Deploying 1 drone detection and countermeasure device at the commanding height forms a drone early warning and defense circle covering 360° horizontally and 5-10 kilometers in depth.

Portable drone detection and countermeasure equipment is simultaneously deployed around the activity site to compensate for regional defense blind spots.
