In military defence, anti-drone systems have been one of the most used methods to protect national security and support the artillery by providing strong defence. Due to the widespread accessibility of drones, illegal activities using it have emerged as one of the most critical issues that militaries need to address. This blog will discuss how anti-drone radar systems protect international borders and actively safeguard national security.
What is an Anti-drone system?
Unauthorized drones cause critical security hazards and can significantly impact national security. Therefore, installing an anti-drone system can identify, track and disarm the drone from the unauthorized area and can jam its signals. Using an anti-drone Radar system, the process of locating and jamming the drone becomes easier.
Why is it important to protect international borders?
When it comes to the protection of international borders, it raises the question of national security. To deal with issues like terrorism, illegal immigration, and smuggling, the involvement of the army and other defense mechanisms becomes crucial. Hence, criminals and terrorists use drones in border areas to disrupt national integrity.
1. Reduce Terrorism:
Borders are a crucial point where potential terrorist activities can take place. Therefore, protecting the border to counter-terrorism is important to provide security from outside forces.
2. Prevention of Smuggling:
Border areas are highly prone to be penetrated with the objective of smuggling activities. Therefore, monitoring borders using anti-drone radar systems will reduce the scope of smuggling and illegal trafficking.
3. Regulating illegal immigration:
Using borders, criminals illegally immigrate to a land with the potential objective of harm. Hence, securing the border using the anti-drone system is essential to restore national security.
How does an anti-drone system help in defending borders?
Combating unauthorized drones using anti-drone radar systems will help enhance border security. Plus, it will also enhance the scope for increased detection and geofencing. These advanced methods will contribute to safer airspace and reduce the harm of potential air attacks on border areas.
These are how anti-drone systems can protect the international border:
Detecting Audio
Drones make a particular sound of specific frequencies, which can only be detected by special devices. Anti-drone systems with acoustic sensors can detect the sounds coming from the drones. Plus, the anti-drone systems have microphones to capture sounds located at short distances. In other words, an anti-drone radar system can detect drones that do not even emit radio signals using acoustic sensors.
Jamming Unauthorized Drones
Using electromagnetic technology, anti-drone systems can detect and jam the network of unauthorized drones. On top of that, drone jamming guns can jam the signal of the unwanted drones that they receive from their operator. The drone-jamming guns use technologies like radio frequency to disrupt the navigation and communication of unauthorized drones.
Geofencing
Using GPS technology, anti-drone radar systems create virtual fencing that acts as an invisible barrier in the airspace. Geofencing combines multiple GPS Sensors and communicates with local radio frequencies.
Neutralizing Unwanted Drones
One of the main countermeasures of anti-drone radar systems is neutralizing the unwanted drones within the network. Many anti-drone systems armed with high-optic devices are used in defence to neutralize or take down drones.
Thermal Detection
Though it is a comparatively older technology, thermal detection is highly capable of identifying drones and their operators in a remote location. Security personnel operating counter-drone systems can use thermal detectors to identify the correct location, even if the drone is located in the airspace.
Technologies used in anti-drone systems
Anti-drone systems combine a handful of technologies that can deliver wider protection by detecting and tracking unwanted drones in restricted areas.
Radar
The anti-drone radar system is the most effective technology that helps detect unauthorized drones, no matter how stealthy they are. Radars emit radio signals and then wait for other signals to be captured. However, radars do not capture signals coming from small targets; it is mainly designed to track large objects.
Radio Frequency (RF)
RF analysers are primarily useful in receiving radio signals from drones. Plus, advanced drones can even locate the MAC address of the unwanted drones and locate the controller. However, this technology can only help in short-range operations and can fail in crowded areas where multiple RFs are there.
Acoustic Sensors
This counter-drone system involves microphones to detect sounds from drones. The pros of using this technology are these devices are swiftly deployable. Moreover, acoustic sensors are functional in detecting autonomous drones without emitting any RF.
GPS Spoofing
GPS spoofing is utilized against unauthorized drones by creating fake signals which prevail over the signals emitted from satellites used by the drones.
Drone Jamming Guns
Drone jamming guns in anti-drone radar systems disrupt the radio frequencies from the drone. Plus, they can override those frequencies by using electromagnetic noise. When deployed in no-fly areas, drone-jamming guns disrupt legitimate signals of unauthorized drones located in nearby areas.
Final Thoughts
In conclusion, the anti-drone radar system is a highly effective system which helps to protect border areas and international airspace. Providing a solid defence, these devices are becoming reliable in protecting international borders and providing quality surveillance.
Using these technologies, modern military defence is becoming stronger to protect national security and ensure peace.
