However, not all drone activity is beneficial. Drones can be used for unauthorized or malicious purposes, from unauthorized surveillance to smuggling. Others even disrupt commercial or military operations.
Anti-drone technology is a means to stop unauthorized drone activity. There are many ways to bring down unauthorized drones and track and apprehend their users. This article explores key aspects of anti-drone technology, including:
- What is Anti-Drone Technology?
- What are the Key Components of Modern Anti-Drone Systems?
- How Do Anti-Drone Weapons Work?
- What are the Military and Commercial Applications of Drones?
- Counter-Drone Technologies in Action
- What are the Advantages and Drawbacks of Anti-Drone Technology?
What is Anti-Drone Technology?
In a nutshell, anti-drone, or counter-drone technology, is used to counter drones. It includes detecting, classifying, and mitigating unauthorized or malicious drone activity.
The biggest dangers drones can pose are primarily related to privacy, security, and safety. They can threaten critical infrastructure like airports and power plants, and be used for smuggling or espionage.
Anti-drone tools have different functions and perform differently. In addition to detecting and classifying drones, users still need to stop them. Methods for stopping drones range from signal jamming and spoofing to kinetic interception.
What are the Key Components of Modern Anti-Drone Systems?
Anti-drone systems work on three main principles: detection, mitigation, and integration with existing security systems. There are a few main components of today’s anti-drone systems, which are:
1. Detection Systems
The first step in stopping hostile drones is checking if one is nearby. There are four main ways that detection systems can spot drones from a distance:
- Radio Frequency Analyzers – RF analyzers use antennas to receive radio waves. Specific systems can identify standard drone models, while others can identify MAC addresses and controllers.
- Geofencing – Geofencing uses local radio frequency identifiers (LRFID) and GPS networks to tag drones that fly over restricted spaces.
- Microphones – Also called “acoustic sensors”, microphones are another counter-drone technology used to detect the sounds drones make.
- Cameras – Standard RGB or thermal cameras can detect drones during the day or night. Recent advances in resolution and processing power make it easier for cameras to detect drones.
- Radar – Anti-drone radar sends a radio signal and uses the reflection bouncing off objects to determine their location. Specialized radar can easily track down drones.
2. Disruption and Mitigation Methods
Detected drones can be tracked in real-time, with some platforms using AI to distinguish between friendly or hostile drones. If the drone is considered hostile, the next step is stopping the drone and capturing it.
Drone signals can be disrupted, which can result in the drone being easier to catch. Here are a few ways to disrupt drone signals:
- Signal Jamming – Signal jammers are an anti-drone system that disrupts the signal between the drone and its controller. This signal disruption can cause a drone to hover, land, or return home.
- Spoofing – Anti-drone tools send false signals to confuse or hijack the drone. They can force the drone to land or change direction.
- Directed Energy – Lasers or microwave systems are currently being tested as ways to stop drones remotely.
- Kinetic Interception – Physical means, such as nets, projectiles, or other drones, can capture or destroy said drones.
3. Integration with Security Systems
An anti-drone system is most effective when integrated with other security systems. Security teams benefit from adding drones to their regular patrols, which lets them review drone footage and increase coverage areas.
What are the Different Types of Anti-Drone Devices?
Counter-drone technology aims to disrupt drone signals and intercept them to track down their controllers. Security teams can utilize more than one type of anti-drone device to monitor areas in real-time, such as:
1. Jammers
Signal jammers emit false signals to force drones to hover, land, or change directions. They work by interrupting the signal between the drone and its controller.
Jammers can be mobile or stationary. Recently, law enforcement agencies worldwide have been using mobile jammers to disrupt drone signals and make them easier to catch.
2. High-Power Microwave Systems
The use of microwave signals to intercept drones can make intercepting them more sophisticated. Microwave blasters can shoot intense bursts of microwave radiation to destroy drones’ electronic components.
However, it’s worth noting that while this drone disruptor technology is powerful, it’s also expensive. On top of that, these high-power systems are also stationary.
3. Anti-Drone Lasers
In recent years, high-energy laser systems have become more common as a counter to drones. They work like the aforementioned microwave systems in that they aim to destroy the drone’s electronics, but they use lasers instead.
However, much like high-power microwave systems, these are also power-intensive and expensive. As a result, they are often used only in military applications.
4. Drone-Catching Nets
Drone nets are the most accessible anti-drone device for most businesses and security teams. While nets are a reasonably traditional method, they work exceptionally well in tangling drone propellers.
The downside of nets is their limited range compared to their more expensive anti-drone counterparts. This limited range means they are used alongside other detection and disruption systems, such as mobile signal jammers.
How Do Anti-Drone Weapons Work?
With drones becoming so popular for commercial, military, and civilian use, anyone can get one. However, it also means drones are more likely to be used for unauthorized purposes.
Anti-drone systems are used to catch or neutralize drones. There are three main ways that anti-drone weapons work:
1. Kinetic vs. Non-Kinetic Systems
There are a few differences between kinetic and non-kinetic systems. For one, the former uses physical projectiles, such as nets, missiles, and counter-drones. However, these can create debris and risk collateral damage.
For non-kinetic methods, security teams have access to electronic interference. These can range from RF jamming to EMP (electromagnetic pulses) to disrupt a drone’s onboard electronic systems.
2. Directed Energy Systems
High-powered lasers and microwave systems are another type of anti-drone weapons used for neutralizing hostile drones.
In a nutshell, directed energy systems emit massive energy bursts to destroy a drone’s onboard electronics. Two popular examples of directed energy systems include lasers and microwave systems.
3. Counter-Drone Interceptors
In some instances, the best way to counter drones is with your own drones. These interceptors are connected by AI and swarm technology to anticipate flight paths, encircle, and bring down hostile drones.
Many military and security teams are investing in these defense drone systems to stop unauthorized drone activity. While they are relatively new, they can be helpful in cases when the previously mentioned systems fail.
What are the Different Military and Commercial Uses of Anti-Drone Technology?
Drones are becoming more advanced and accessible, making users more likely to fly drones into sensitive or critical infrastructure. As a result, drone security is becoming a bigger part of many industries worldwide.
Here are the ways anti-drone systems are used worldwide:
1. Military Installations
