The increase in the demand for civilian drones has brought new challenges to the security of the aviation industry. Besides, it poses a great threat to the security of celebrities and top government officials in the country. It might be an amateur drone pilot or a terrorist – the threat level remains similar.
Now, security agencies must counter possible drone attacks on valuable persons and sites. The latest drone-blocking technologies have opened the opportunity to detect and stop drones. Using GPS spoofing technology, now you can stop drones from attacking their targets.
The blog will take you through some of the best drone-blocking technologies to help you explore your options to stop rogue drones.
What is GPS spoofing and how does it help in drone blocking?
It involves emitting stronger false signals on GNSS frequencies to provide false location information to drones. These false signals overpower its legitimate signal and make the drone the overpowering signal is the legitimate one.
You can use GPS spoofing technology to stop the drone or change its course of direction. Security agencies can use the technology to detect rogue drones and avert potential security threats.
Similar to GPS spoofing technology, there are several other advanced technologies that you can use for drone blocking. Let’s take a look at these technologies.
Radio Frequency (RF) Analysis
The technology involves multiple antennas to catch radio frequency-based communication between the drone and its controller. The sensors used in the system analyse the radio frequency spectrum. The technology is so powerful that it can even detect the MAC address of the drone and its handler.
In legal proceedings, you can use this type of information to prove that the drone was present in that given location and date.
Its low-cost operation makes it the most effective. You can use sensors and detect radio frequencies to detect any possible presence of drones in the area. However, you might find it less effective in areas with high radio frequencies. The multiple presence of RF makes it difficult to triangulate the drone.
Nonetheless, the technology works just fine if you combine it with other drone-blocking technologies.
Drone Detection Radar (DDR)
It is a Frequency Modulated Continuous Wave (FMCW) – based drone detection technology. The Drone Detection Radar system can detect drones of mini or micro levels and also UAVs. The system is so effective that you can carry and install it to monitor areas with 360° coverage.
The technology involves burst radio signals and catches the echo to detect drones and other unidentified objects. With this technology installed to monitor the airspace, you can detect and track drones from miles away. However, one challenge of the drone is not being able to distinguish tiny birds from drones.
However, modern advancements in drone detection technology may help to overcome this challenge.
Acoustic Detection System
In this drone detection technology, powerful microphones are used. Powerful acoustic sensors help to detect sounds that a drone produces when it flies. The powerful sensors detect and analyse the sounds and determine their direction.
The technology becomes more powerful when used in combination with RADAR, camera or RF technologies. With the Acoustic Detection System, you can detect manually or automatically operated drones.
The drone-blocking technique starts with detecting the drone. The Acoustic Detection System does that perfectly. It can even differentiate between ground noises and drone noises. However, if the area is full of high-frequency noises, detecting drones becomes challenging.
Optical Sensor Technology
Like humans detect drones or any flying objects with bare eyes, this technology also does the same. Optical sensors also combine infrared and thermal imaging systems to detect drones of various shapes and sizes.
Using AI-powered technologies, optical sensing for drones has improved. With high-resolution image production, you can now easily detect drones by their images. You can get detailed data on drone class size and specifications. Detecting drones in the dark could be challenging, so the system now uses a thermal imaging system.
The technology is again useful in capturing drone images and using them as forensic evidence.
Conclusion
In conclusion, the above technologies such as GPS spoofing, radar, and RF analysis can help in drone blocking. You can use any of the technologies or make a combination of different technical tools to safeguard your airspace from rogue drone attacks.
These technologies not only help to detect drones from miles away but also track and neutralize them. Some tools come in a portable size for you to carry to places and set up for better protection from drones.
Be it a private space or national aerospace you are protecting, leveraging these drone-blocking technologies is necessary. Analyse the settings of your area and choose a suitable drone-blocking tool.
