In recent years, the global drone industry has gained significant popularity across various sectors.
Some reports project that the global drone market will expand from 34.4 billion dollars in 2023 to 87.5 billion dollars in 2033. It is quite evident that drones are gaining traction in civilian and commercial sectors with cutting-edge technology.
Most people perceive drones as helpful gadgets but unauthorized drones can be a threat to public safety, national security, and privacy. We shouldn’t forget that drones can be misused in numerous ways. That’s why it is necessary to acknowledge the threats which can be caused by the misuse of drones.
To safeguard against security risks, tech-enabled protection is essential. Here’s where anti-drone systems come into play. For example: anti-drone cameras are widely used to detect unauthorized drones. In this blog, we are going to cover the topic of how anti-drone systems can ensure public safety.
Understanding the Threats Posed by Drones
Let’s begin by understanding the potential threats.
Unauthorized surveillance and privacy violations:
Drones can be utilized to their full potential to monitor someone or something without permission or legal jurisdiction. It is an invasion of privacy which can be completely illegal. Unauthorized surveillance can be used for several malicious purposes, so taking that into consideration an anti-drone system has been developed.
Airspace intrusions:
There have been instances where drones were caught flying near airports, military bases, and government buildings without any prior permission or authorization. It is a violation of international law and can pose a threat to national security as well as civilian aircraft.
Some intrusions have been done intentionally with illegal purposes and some were done unintentionally due to navigational error and technical malfunctions.
Use in Criminal Activities:
For terrorism and smuggling, drones are one of the best gadgets to recce illegally. Terrorist organizations often use drones to find out information about particular areas. Drones are also weaponized with explosives to carry out attacks. Smugglers also use drones to smuggle illegal things from one place to another.
Disruptions at Venues:
Drones can also cause disruption at public events, concerts, or stadiums. They can cause injuries to the crowd, bypass security perimeters, record people or events without consent, or interfere with communication systems. These are some major ways through which drones can cause disruptions in venues. A system in place for stadium drone detection will be highly useful here.
Key Components of Anti-Drone Systems
The anti-drone system consists of technologies designed to detect, track, or mitigate the threat. The purpose of anti-drone systems is to protect sensitive areas, high-profile events, and infrastructures.
Detection Technologies
First, we will discuss the detection technologies of anti-drone systems.
Radar Systems:
These systems emit radio waves that bounce off drones and other objectives. The purpose of using radar systems is to detect and track the movement of drones. The reflected areas are analyzed to determine the presence, speed and path of the drone.
Radio Frequency Scanners:
Drones emit electromagnetic signals which can be detected by radio frequency scanners. The presence of drones and their operational frequency can be detected by analyzing these signals.
Electro-optical & Infrared cameras (anti-drone camera):
These cameras capture light and convert it into images but they differ in the type of light they detect.
EO cameras detect visible lights, and IR cameras detect infrared lights.
EO cameras produce images that we normally see with our eyes, but IR cameras capture heat radiations that the objects emit. These are also called anti-drone cameras.
Acoustic sensors:
This sensor is designed to detect the sound of drones. By analyzing the sound signature, and using a combination of other sensors drones are tracked down with high accuracy.
Identification & Classification
Now the question arises, how can a drone be identified if it is an authorized one or not? Let’s find out the ways.
Authorized drones have visible registration numbers and IDs, with a clearly marked logo. They also have the branding of the authorized operator.
Unauthorized drones do not have any type of visible registration numbers or IDs. They often have no branding of the authorized operator or marked logo.
Methods of Neutralizing Malicious Drones
We have segmented the process of neutralizing malicious drones into two parts. First is electronic countermeasures, and second is physical interception.
Electronic Countermeasures
To disrupt the communication between the drone and its operator electronic countermeasures are used. Electronic countermeasures can make drones lose their control completely. The system also includes a GPS spoofing technique which helps to mislead the navigation systems of unauthorized drones.
Physical Interception
There are also certain ways through which unauthorized drones can be physically captured and destroyed. For example: net guns, laser systems, and projectiles. Net guns are used to capture rogue drones, and laser systems are used to disable or destroy drones.
Role of Anti-Drone Systems in Public Safety
Now we will list down some note-worthy roles in which anti-drone systems are widely used.
- To protect critical infrastructures such as airports, government infrastructures, power plants, military bases, etc.
- To ensure security at public events such as live concerts, sports events, political rallies, or festivals. For example: stadium drone detection can help ensure safety in a stadium full of audience and players.
- To prevent smuggling across cities, states, as well as countries.
- To block drones for data theft that falls under the category of cyber security threats.
Challenges & Future of Anti-Drone Technology
Just like every system has its pros and cons, anti-drone technology also has some challenges. First of all, deploying anti-drone measures can raise legal as well as ethical concerns. Primarily it can cause civilian casualties and privacy violations.
The system can also be misused and can lack clear regulatory frameworks. That is why executing by following the guidelines is crucial.
In the near future, more AI-driven drone systems will be developed to enhance the level of accuracy and the future policy and regulations for drone control will be redefined.
Anti-Drone System is Needed to Ensure Public Safety
There’s no doubt that anti-drone systems are crucial to ensure public safety on different levels. First of all, detection is important for which an anti-drone camera would be a very useful tool.
The anti-drone systems have been designed to acknowledge all the threats that can be posed by drones. All the key components of the system help in execution. Detection technologies in anti-drone measure the level of accuracy.
With proper methods, one can neutralize malicious drones. Though the anti-drone system contributes to ensuring public safety, it has its own set of challenges. Undoubtedly, the future and anti-drone technology seems quite brighter with the evolution of advanced technology.
