As drone operations become increasingly common across public safety, critical infrastructure, and security domains, the need for reliable airspace awareness is more urgent than ever. The growing use of both authorized and unauthorized drones - combined with rising geopolitical tensions - has pushed governments, critical infrastructure managers, and private security operators to rethink how they monitor and control low-altitude airspace.

To ensure safety, security, and operational continuity, drone operators and airspace managers must combine three layers of capability:

1. Drone Operations Management (e.g., AirHub’s Drone Operations Platform)

2. UTM/U-space Connectivity (for situational awareness of cooperative traffic)

3. Drone Detection Systems (for visibility into non-cooperative or unauthorized drones)

This blog provides a deeper dive into the different types of drone detection technologies and how AirHub supports organisations with both software integration and regulatory guidance to ensure a full airspace picture.

Why Drone Detection Is Essential

While U-space and Unmanned Traffic Management (UTM) systems provide valuable information about cooperative drone traffic - i.e., drones that voluntarily share their flight data or have filed flight plans - they don’t cover all drones.

A significant number of drones operate non-cooperatively: they may not broadcast their position, may not comply with Remote ID requirements, or may even be deliberately hostile. Whether due to technical limitations or malicious intent, these drones pose a growing challenge for airspace security, especially near critical infrastructure.

That’s where drone detection systems come in: to fill the blind spots left by UTM and give operators real-time awareness of all drone activity, not just the compliant ones.

The Different Types of Drone Detection Technologies

There is no one-size-fits-all solution for detecting drones. Different environments and use cases require different approaches. The most common types of detection technologies include:

1. Radio Frequency (RF) Detection

These systems scan for signals transmitted between a drone and its remote controller. They are passive (i.e., do not emit signals themselves) and can identify make/model, location, and often the pilot's location.

• Pros: Widely used, cost-effective, and easy to deploy

• Cons: Ineffective against autonomous drones or those using encrypted or frequency-hopping signals

2. Radar Systems

Radars detect objects by bouncing radio waves off them, similar to conventional air traffic surveillance systems. Specialized low-altitude drone radars are optimized to detect small, slow, and low-flying objects.

• Pros: Effective in wide open areas and can track multiple targets

• Cons: May struggle in cluttered urban environments or with small drones in certain conditions

3. Optical/Visual Detection (EO/IR Cameras)

These systems use electro-optical or infrared (EO/IR) cameras and advanced computer vision to visually detect and track drones.

• Pros: Can provide visual confirmation of drone presence, useful for classification and evidence

• Cons: Limited range, weather dependent, and often require line-of-sight

4. Acoustic Detection

These sensors listen for the unique audio signatures of drones using microphones and audio analysis software.

• Pros: Useful in GPS- or RF-denied environments

• Cons: Limited range and susceptible to environmental noise (wind, traffic, etc.)

5. Hybrid Systems

Modern installations often combine two or more of the above technologies to cover each system’s weaknesses and increase detection reliability.

Toward a Unified Airspace Picture

A true “airspace picture” means knowing where your own drones are, where cooperative traffic is operating, and where unauthorized drones may be active. AirHub’s approach is built around this principle of multi-layered awareness:

In our Drone Operations Center (DOC), users can:

• Plan and monitor drone operations

• Connect to U-space/UTM systems to receive live cooperative traffic data

• Integrate with drone detection systems to detect non-cooperative or unauthorized drones

• Overlay geozones, restricted areas, and airspace structures to improve operational planning

This combination ensures that airspace managers, security teams, and public safety operators get a comprehensive view of what’s happening in the air - especially around sensitive sites like ports, industrial zones, railway hubs, energy infrastructure, and border areas.

Our Consultancy Services: Building Strategy and Compliance

In addition to technical integration, AirHub Consultancy supports government agencies, critical infrastructure operators, and private companies in:

• Developing policies and procedures for integrating drone detection into security and operations workflows

• Designing airspace protection strategies around critical infrastructure

• Assessing counter-drone and detection technology options

• Supporting regulatory alignment with EU and national laws (e.g. privacy, data processing, evidencing intrusions)

• Training teams to understand detection data and integrate it with incident response

We also support the development of risk-based operating procedures for drone operations near sensitive areas, including SORA-based risk assessments and Emergency Response Plans (ERP) that take into account the presence (or absence) of drone detection capabilities.

Final Thoughts

Drone detection is no longer optional. It’s a critical capability for any organisation operating drones, managing critical infrastructure, or tasked with securing sensitive airspace.

But detection alone isn’t enough. You need integration, interpretation, and action. That’s why AirHub combines detection integrations, UTM connectivity, and operational planning in a single platform - supported by a team of consultants who understand the regulatory, technical, and operational landscape.
