Scalable Perimeter and Area Protection: Acoustic Sensor Network for Strategic Defense
In today’s conflicts, defending the perimeter is no longer about walls and fences alone. Threats arrive from the air—fast, cheap, and hard to predict. FPV drones, loitering munitions, and larger aerial systems have become central tools of disruption, and they’re not going away. To counter this, Squarehead Technology’s acoustic systems can work as a scalable sensor networks that bring persistent surveillance and resilience to borders, infrastructure, and frontline positions.
Sentry Post: Man-Portable Drone Detection System
On today’s battlefields, small patrols and dismounted units are often the most vulnerable. At night, when visibility is low, or in contested terrain where threats can appear without warning, maintaining constant vigilance is both exhausting and impractical. The Discovair G2+ from Squarehead transforms this challenge, establishing an immediate acoustic safe zone that provides 360° surveillance and early warning against drone threats.
Point Defense: Rapidly Deployable Acoustic Shield
Modern units face constant threats from drones and other aerial systems, even when stationary for only short periods, for instance during a column halt. In these moments, point defense — the protection of a limited area or unit for a short duration — becomes critical. Protecting troops and assets without adding to the burden of constant watch is essential. Discovair G2+ delivers a powerful protective dome of awareness that alerts soldiers the moment a threat enters their perimeter — enabling rest, repositioning, or safeguarding of assets with confidence.
Acoustic BLISTER DETECTION in ALUMINUM EXTRUSION
In high-volume metal forming processes such as extrusion, rolling, and pressing, precision and repeatability are paramount. Yet, material defects can emerge. One particularly elusive and damaging defect in aluminum extrusion is the formation of blisters, also known as pinhole blowouts, localized weak spots caused by trapped gas within the metal. Traditional quality assurance tools often fall short in detecting these faults in real time. However, these defects often produce a telltale sign: sound.
Acoustic FEATURE TRENDING for CONDITION MONITORING
What happens when parts of a industrial processes begin to deteriorate? Often, the sound signature of equipment will change—gradually over time, or suddenly through acoustic events that signal faults or failures.
In industrial facilities, a variety of sensors are in place to measure performance and stability. Despite this, one of the most vital diagnostic tools remains the operator’s ear, which is trained to recognize subtle shifts in how equipment sounds. Squarehead can replicate this sensory expertise digitally.
Fault Detection in SERIAL PRODUCTION: Golden Sample SOUND SIGNATURES
In the world of serial production, especially when dealing with rotating equipment like pumps, fans, and motors, precision and repeatability are everything. Before any unit leaves the factory, it typically undergoes a series of quality checks. One of the most telling – and traditionally subjective – is the acoustic test: does this unit sound like it's supposed to?
QUALITY CONTROL for Production UP-TIME and PRODUCT QUALITY
Can you hear repeating failure in your production line or process facility? What about the production equipment you use? If you can tell in an instant when something is off in the sound signature, where the sound is a key indicator of faults that might not meet the standards of the finished product, Squarehead can digitalize and automate that human sense and experience – even in extremely noisy environments.
R&D SOUND TESTING during Product Development
When developing a new product, every detail matters, including how the product sounds. Whether it’s the hum of a motor, the whirr of a fan, or the subtle vibrations of moving parts, noise isn’t just a byproduct – it’s a performance indicator. In fact, unexpected or undesirable sound emissions during R&D can signal hidden issues with design, component compatibility, or mechanical tolerances.
The Role of ACOUSTIC SITUATIONAL AWARENESS in AUTONOMOUS NAVIGATION
On autonomous vessels, the accurate detection, localization, and monitoring of sound sources become critical for effective operation and safety management. Up until now, the industry has to some extent relied on personnel and their senses to navigate safely on the ocean. As we move toward full autonomy, these senses need to be replaced, including the auditory capability. The ability to clearly understand auditory environments can dramatically improve operational effectiveness, reduce risks, and support the transition to autonomous navigation in maritime transport.
PROTEAS and Squarehead
In an increasingly complex and fast-evolving security landscape, European Special Operations Forces (SOF) must be equipped with highly adaptable and integrated command structures to stay tactically competitive. The PROTEAS project addresses this urgent need by developing the first-of-its-kind modular and scalable command post tailored for SOF missions. At Squarehead Technology, we are proud to be part of this effort.
ADVANCED PERIMETER DEFENSE with Acoustic CUAS
We collaborate closely with border control forces, enhancing their protected perimeters with top-notch acoustic drone detection. Discovair revolutionizes the field by delivering accurate slew-to-cue detections, seamlessly directing high-precision sensors towards identified targets.
PASSIVE DETECTION Against Drones in Conflict
Discovair has been deployed in conflict, supporting the needs of allied forces to detect both small, and large drones. Detection allows forces to mitigate the threat, whether it is from a small ISR drone - or from a fire-and-forget kamikaze drone. The lightweight, and small physical and power footprint, allow for mobile and dismounted use, always using the sensors where they are needed the most.
PROTECTION of MILITARY AIRPORTS
Fighter jets are most vulnerable when they are sitting on the ground. A small drone can be a thousand-dollar weapon against a 100-million-dollar weapons system. Discovair provides near-field detection capability for high-value assets. When combined with an electronic warfare or kinetic kill effector, it forms a complete kill-chain that guards the high value asset.
PASSIVE DETECTION CAPABILITIES for SOF Operations
The Discovair G2 has a small footprint - both in size, weight and power - and can be brought into most special forces’ operations. By employing multiple units and displaying alarms and user interface on a body worn phone display, the system provides an easy-to-use passive drone detection system that gives full hemispheric coverage - against any drone - providing the team with an invisible safety shield
