Drones and their varied applications have taken the world by storm, gaining widespread use in industries like logistics, security, agriculture, photography, and even meteorology. However, with this, the threat of malicious activity using drones is also on the rise.
Thus, a way to combat unauthorized drones is the need of the hour. Making strides towards this goal is anti-drone technology.
A 2024 report stated that the global anti-drone market stood at USD 2.31 billion, with North contributing 46% of the total revenue. However, this is expected to grow with a CAGR of 27.52% and reach USD 26.26 billion by 2034.
From age-old radars and jammers, the sector is quickly making strides to implement AI and automation to address drone threats.
The Evolution of Anti-Drone Detection Technology
From governments to law enforcement agencies, detecting, tracking, and neutralizing unauthorized drones is a priority for all. While the cornerstone of drone detection is radars, the technology has, since then, moved forward and grown.
Modern anti-drone systems have evolved and now include the following:
• Radar Detection
By transmitting electromagnetic waves and analyzing the waves that are reflected back from drones, radars can accurately detect invading drones, track their movements and obtain drone data, such as distance, speed, and altitude.
• RF-Based Detection
By capturing and analyzing the radio frequency signals that drones emit or receive for communication, RF detectors can detect, identify and track the presence and movements of invading drones efficiently.
• Electro-Optical and Infrared Sensors
Using high-resolution imaging and thermal sensors, these devices hone in on the location of the drones. Thus, these offer precise tracking even in low visibility scenarios.
• AI and Machine Learning (ML)
By leveraging ML algorithms, AI-based anti-drone devices can analyze the behavior of drones and predict their flight patterns. Thus, these devices go one step beyond detecting just unauthorized drones to detect and neutralize truly malicious ones.
The Role of AI in Anti-Drone Detection
With drones being used for a multitude of purposes, differentiating between them is of the essence. This not only implies authorized and unauthorized drones but also whether or not they are a threat.
To address this, Artificial Intelligence can achieve the following:
AI-Powered Threat Identification
This entails using drone sensor data and footage to detect rogue drones and identify any potential threats in real time. Further, this can also be used to assess the threat level to prioritize and plan an appropriate action.
Deep Learning and Computer Vision
With the help of machine learning, anti-drone systems can be made intelligent and autonomous. This involves properly detecting a drone threat using inputs from radars, RF detectors, cameras, flight patterns, and drone behavior.
Real-Time Automated Response
Using inputs from drone detection systems and analytics of the same, the anti-drone system can take action on its own automatically. This helps initiate a response and trigger alerts, thus reducing the response time.
Automation in Anti-Drone Systems
Beyond the use of AI, anti-drone systems stand to gain a lot from automation. Some of the most prominent automation technology in use are:
Sensor Fusion for Enhanced Detection
High-res cameras, radars, RF detectors, and acoustic sensors provide accurate data of the drone. By using multiple sensors, anti-drone systems can improve accuracy and provide a better view of the drone’s position and threat level.
Automated Drone Neutralization Methods
Once the sensors provide data on the threat level of the unauthorized drone, automated neutralization methods provide a prompt response. This involves using a drone jammer or navigation spoofer to neutralize the drone, forcing it to either land, return or fly away to a preset location.
Cutting-Edge Anti-Drone Products with AI & Automation
