How a Modular Counter-Drone System Works | IMS 2026 Booth Demonstration

By: Mark Cranmore, Senior RF Interconnect Product Line Manager, Product Management, Infinite Electronics

At IMS 2026, the Infinite Electronics’ team demonstrated how commercially available RF infrastructure components can be combined into a modular counter-drone platform creating the structure for drone detection and threat assessment systems.

The demo highlighted how antennas, RF sensing, environmental protection and supporting infrastructure work together to form a complete system architecture. The modular approach gives organizations the flexibility to configure solutions based on mission requirements while using proven, in-stock technologies.

Key Takeaways

• • Counter-drone systems rely on multiple, layered technologies working together, not a single device.
• • RF sensing provides an early layer for detecting and classifying drone signals.
• • Multi-sensor fusion improves situational awareness by combining RF awareness, radar, video and audio data.
• • Supporting infrastructure such as enclosures, surge protection and mounting systems are critical for reliable outdoor deployments.

Building a Modular Counter-Drone Architecture

The system demonstrated at IMS was designed to illustrate how commercially available off-the-shelf components can be integrated into a complete counter-drone platform. Rather than relying on a single technology, effective counter-drone systems layer complementary sensing, communications and infrastructure technologies to improve detection, assessment and deployment flexibility.

The architecture begins with an outdoor antenna array that receives RF signals from the surrounding environment. Depending on deployment requirements, the system can incorporate multiple antenna types operating across different frequency bands,  and with various propogation patterns to effectively cover the area.GPS and anti-jamming GPS antennas are also added for accurately monitoring sensor location.

These signals are processed by an RF sensor that detects and classifies transmissions based on their frequency characteristics, providing the first step in identifying potential drone activity.

From RF Detection to Threat Assessment

Detecting an RF signal is only part of the process. RF sensor data can feed a fusion platform that combines information from additional technologies such as radar, video and audio systems. By correlating inputs from multiple sensors, operators gain greater confidence when determining whether an object represents a legitimate threat.

Infrastructure Is Critical to System Reliability

RF sensors and antennas may be the most visible elements of a counter-drone system, but supporting infrastructure and interconnects play an equally important role in overall performance and reliability.

Outdoor deployments often require climate-controlled enclosures to help protect sensitive electronics from temperature extremes while simplifying installation through pre-wired configurations and custom connector interfaces. Surge protection also helps safeguard RF equipment from lightning and transient voltage events, while robust mounting systems ensure antennas and supporting hardware remain secure in challenging environmental conditions.

Interconnects that are rugged, capable of withstanding extreme conditions while maintaining minimal loss are critical.  Systems can be mounted by the saltwater or where other caustic conditions exist and degrade over time.  Longer than necessary cable runs with inefficient connectors can induce additional losses in a system.  Combine these degradations and losses will inhibit drone detection to the point that they could be completely missed and result in the loss of life.

By treating enclosures, surge protection, mounting hardware and RF connectivity as integral parts of the system architecture, organizations can improve user safety, long-term reliability while reducing deployment complexity.

Frequently Asked Questions (FAQs)

What is a modular counter-drone system?

A modular counter-drone system integrates multiple technologies—including RF sensing, antennas, radar, video, audio sensors and supporting infrastructure—into a configurable platform. This approach allows organizations to tailor system capabilities to specific operational requirements while simplifying future upgrades and expansion.

How does RF sensing help detect drones?

RF sensors detect and classify radio frequency transmissions emitted by drones, their controllers, and sensor data. By identifying these signals, RF sensing can provide an early indication of drone activity and complement other detection technologies within a layered counter-drone architecture.

Why is multi-sensor fusion important in counter-drone systems?

No single sensing technology is effective in every environment. Multi-sensor fusion combines data from RF sensors, radar, video and audio systems to improve drone detection, classification and threat assessment, giving operators greater confidence when evaluating potential threats.

What technologies are commonly used in a counter-drone system?

Modern counter-drone systems typically combine RF sensing, multi-band antennas, radar, electro-optical cameras, audio sensors, signal processing, surge protection and environmental infrastructure. Integrating these technologies helps create a more capable and resilient detection platform.

Why is surge protection important for outdoor RF installations?

Outdoor RF systems are vulnerable to lightning strikes and transient voltage events that can damage sensitive electronics. Surge protection helps safeguard connected equipment, improve system reliability and reduce downtime in exposed deployment environments.

Why are modular counter-drone architectures becoming more common?

Modular architectures give organizations the flexibility to integrate multiple sensing technologies, replace or upgrade individual components as requirements evolve and configure systems for a wide range of operational environments without redesigning the entire platform.
