The contemporary security landscape is undergoing rapid transformation. Nonetheless, BSS’ passive acoustic solutions provide cost-effective and covert threat detection along with scalable deployment, thereby improving situational awareness across various domains.

Transitioning away from a reliance on defensive firepower, contemporary defence architectures have taken flight from traditional grounds. In this context, cost-efficient solutions for covert threat detection have emerged as fundamental components in any modern security structure. This competitive pursuit of technological superiority has been further intensified by the conflict in Ukraine as well as other geopolitical shifts, sparking accelerated advancements in sensor technology.

Among these, passive acoustic sensors such as BSS’ Komodo and Iguana have gained substantial significance.

A passive advantage

In an article published by the Danish Defence Acquisition and Logistics Organisation (FMI), the department highlights that passive acoustic sensors offer dual advantages, notably their non-emissive detection capabilities and cost-efficiency. The passive design of BSS’ Komodo and Iguana enables the detection of threats such as unmanned aerial vehicles (UAVs), gunfire, and artillery without revealing their own location. Furthermore, the solutions’ cost-effective design enables deployment at higher volumes with reduced logistical requirements compared to active systems, while still providing cutting edge real-time intelligence.

Sensor fusion and system integration

The BSS Komodo and Iguana may be provided as single modular solutions. However, their true utility comes to light when integrated into layered sensor architectures combining radar, optical, and RF-based detection systems. This sensor fusion capability supports layered surveillance strategies, improves threat classification fidelity, and refines overall situational awareness across multiple domains and environments.

Passive acoustic sensors

BSS provides two absolute passive acoustic sensor solutions for both defensive and civilian applications.

Komodo – Acoustic drone detection

BSS Komodo is a passive acoustic sensor system developed for detecting and classifying drones based on their acoustic signatures, including pusher-propelled types like the Shahed 136 and Orlan-10. With a detection range of up to 5 kilometres, the Komodo offers early warnings without emitting signals, making it undetectable to adversaries.

The Komodo is designed for rapid deployment and is low-cost, easy to integrate, and scalable across wide operational areas. It’s simple, robust construction ensures high reliability and resistance to spoofing, as it detects physical sound patterns. Additionally, minimal training is required to operate the solution, making it ideal for both fixed and mobile counter-drone operations.

Iguana – Artillery, gunfire, and explosion detection

The Iguana operates passively and is capable of detecting and locating artillery, gunfire, and explosions. Using an array of microphones, the Iguana triangulates the point of origin with high precision, providing 360-degree situational awareness.

The solution enhances responsiveness in dynamic environments by enabling threat identification and supporting timely counter-operations. Like the Komodo, the Iguana is built for mobility and complex conditions and integrates easily with radar, RF, and layered defence architectures.

Looking ahead

As threats evolve and become more sophisticated, the importance of reliable, covert, and scalable detection systems cannot be overstated. In this context, BSS’ passive acoustic sensors exemplify the future of passive acoustic detection technologies' by providing critical, real-time intelligence without compromising operational security.
