The introduction of innovative tools and technologies contributed to the success of modern warfare. An Unmanned Aerial Vehicle (UAV) is an advanced controlled vehicle used in defence systems for surveillance and close combat operations. Anti-UAV systems are deployed to track and control the movements of a UAV before it causes harm. Now, the question arises, how does the anti-UAV system work in defense? Well, in this blog, we have covered the operations of anti-UAV systems in detail.  

What are anti-UAV systems?

The anti-UAV systems are useful in neutralising and tracking UAVs considering the capability of disrupting them. In modern countries, anti-UAV systems play a key role in the combat environment of warfare. 

Drones are starting to pose threats to a nation’s civilian safety. For example, drones or UAVs have become synonymous with unauthorized surveillance and smuggling activities. Besides, with the implementation of modern technologies in warfare, a simple UAV can be turned into a guided missile. 

Therefore, using the detection ability of the anti-UAV systems, countermeasures are activated to disrupt the UAVs. 

As an alternative measure, the installation of anti-drone rifles is common to disrupt unwanted drones or UAVs by disabling and destroying them. 

Why it is important to deploy Anti-UAV Systems

Drones or UAVs are significantly threatening to a nation’s security. Unauthorized UAVs can carry explosives and execute surveillance missions which compromise civilian safety.

Reasons behind deploying Counter UAV systems in defense include:

  • International Security

International border security is an essential role of anti-UAV systems as it restricts any unauthorized UAVs from entering the national border. For enhanced security, the employment of anti-drone rifles is common in border areas.

  • Protection of Important infrastructures

Using counter-UAV systems, important structures are protected from harmful drones. Anti-UAVs cautiously remove or disrupt drones which can cause harm by early detection. 

  • Building a strong Air Defense

Drones can cause serious harm to aircraft by crashing into them and detonating the targeted aircraft. So, anti-UAV systems are deployed to take down harmful drones and protect aircraft. 

Integrated control of the counter UAVs allows them to jam the networks of the prohibited drones to strengthen air defense measures. 

  • Restricting Terrorism Activities

Weaponized UAVs can inflict serious harm to military operations conducting attacks. Therefore, militaries use anti-UAV systems to identify and destroy those hostile drones.

  • Availability on different platforms

Counter UAV devices can be both ground-based and handheld. Ground-based anti-UAV systems generally work from stationary positions. On the other hand, handheld systems like anti-drone rifles are commonly used in disrupting drones or taking them down. 

Counter-drone systems are also capable of intercepting the frequency of unauthorized drones which has been ideal in combating the harms of weaponized drones. 

How does the Anti-UAV Systems Work in Defense

As discussed above, anti-UAV systems have different roles in defense, from protecting military bases to neutralizing enemy drones. The anti-UAVs work in a complicated process, with multiple systems combined in a single device. Here is how it works:

  • Detection systems:

First and foremost, the basic role of anti-UAV systems includes basic detection and identification of the unauthorized drone. A complicated RADAR system assembled into the counter UAVs helps them detect the drone’s movement. On top of that, complex algorithms in this setting differentiate drones from other moving objects like birds. 

Secondly, Technologies like electro-optical devices and infrareds support anti-UAVs to identify the presence of unauthorized drones by visuals and heatmaps. Plus, many advanced anti-UAV devices use detection techniques by combining powerful sensors for precise and accurate tracking.  

  • Countermeasure Systems:

Anti-UAV systems include different countermeasure systems to prevent the UAVs from potential threats. However, most of the countries regulate drone retaliation strongly, despite the availability of advanced technologies. 

RF (Radio Frequency) jamming is a helpful countermeasure which allows anti-UAV systems to disrupt the radio link between the harmful drone and its operator. Technically superior jammers in anti-UAVs can even make the drones uncontrolled or static pre-programmed locations. However, RF technology can only work in a short range. 

GPS spoofers are also a good option which sends signals to the unwanted UAVs by misleading them and altering the original communicational signal.  However, GPS spoofers tend to disrupt other signals beyond the targeted drones. 

Therefore, it is most suited as a warfare countermeasure and not commonly used in civilian operations. 

  • Operating:

The main operation of an anti-UAV system includes radar-based navigation to track and detect prohibited drones. Optical cameras spot the UAVs and detect their movements. Additionally, many advanced anti-UAVs can activate countermeasure systems automatically. 

Conclusion

In conclusion, the future of anti-drone systems is becoming essential while national security is in question. Alongside defense and military operations, counter-UAVs help in protecting establishments with national importance. Anti-UAV systems are becoming key in removing the alarming threats of UAVs or drones during warfare. Using advanced detection and jamming technologies, counter UAVs play a superior role in elevating the level of security.
