New radar technology enables rapid, high-performance drone detection for security teams on the move
Compact Solutions for Evolving Threats
As drones become faster, smaller, and more accessible, the need for flexible and mobile detection systems has grown. Traditional drone detection systems, often built on large, fixed infrastructure, can’t always keep up with the speed and unpredictability of new threats. Now, advances in Low-SWaP radar technology—radars that are small in size, light in weight, and low in power use—are changing that.
These new systems are engineered to be portable and energy-efficient. This makes them suitable for a wide range of security scenarios, including mobile convoys, emergency response, and pop-up perimeter defense at large public events.
Why Low-SWaP Matters
Low-SWaP radar technology focuses on three key features:
-
Size: Compact enough for installation on vehicles or temporary structures.
-
Weight: Light enough to be mounted without specialized gear.
-
Power: Operates on batteries or small generators, eliminating the need for large power sources.
These radars offer full functionality with fewer requirements, making them ideal for dynamic deployments. According to AirSight, a provider of drone detection systems, this shift has major implications for security forces needing to respond quickly.
AirSight and Echodyne: Fast, Flexible Deployment
AirSight’s AirGuard platform is one example of how Low-SWaP radar is being used in real-world applications. The system integrates Echodyne’s EchoGuard radar panels with other sensors for a full-spectrum drone detection solution.
The entire unit can be deployed in minutes and run on portable power, making it ideal for short-term operations or field conditions. “Low-SWaP radars allow us to push drone detection capabilities to the tactical edge,” said Arya Rahmanian, Testing Coordinator at AirSight. “These systems can be vehicle-mounted, trailer-based, or handheld, providing high-performance radar tracking without the heavy power and infrastructure footprint. That agility is critical for modern threat landscapes.”
Technical Advantages of Low-SWaP Radar
The benefits of Low-SWaP radars extend beyond size and power:
-
Quick Setup: Systems are ready in seconds to minutes.
-
Efficient Power Use: Runs for extended periods on compact sources.
-
Adjustable Coverage: Can be moved or re-aimed as threats change.
-
Sensor Integration: Combines easily with RF sensors, cameras, and Remote ID systems.
These features are especially useful in complex environments where threats may shift rapidly or where permanent infrastructure isn’t available.
Meeting the Needs of Tactical Environments
Low-SWaP radars are also proving useful in locations where other systems might fail. These include:
-
GPS-denied or RF-heavy areas
-
Temporary work zones or events
-
Mobile operations requiring real-time drone tracking
With these capabilities, teams can secure airspace even in difficult environments, while maintaining mobility and responsiveness.
A Strategic Shift in Drone Detection
Drone threats are no longer limited to fixed locations. As drones evolve, so must the tools used to detect them. Low-SWaP radar technology represents a new generation of mobile defense tools, offering high accuracy without the usual power and space demands.
This shift in technology aligns with the growing need for adaptive and scalable security strategies. By giving security teams more options for where and how they deploy drone detection, Low-SWaP radars are helping shape the future of aerial threat response.
