Heimdall Tactical Multi-Modal Sensor Cluster (HUGIN & MUNIN) is an ultra-low SWaP, man-portable acoustic-optical fusion situational awareness and counter-UAS (C-UAS) system. It integrates passive acoustic array and multi-spectrum optical surveillance modules, equipped with on-device edge computing and proprietary AI classification algorithms. The system delivers continuous, real-time, zero-emission covert monitoring and target tracking capabilities for contested environments, and is widely applied to defense security, border surveillance, maritime protection and other scenarios featuring complex electromagnetic interference, blocked line of sight and harsh weather.
Heimdall is a fully passive Multi-Modal fusion detection solution composed of an acoustic sensing unit (HUGIN), an optical sensing unit (MUNIN) and an integrated sensor cluster. Designed for forward-deployed dismounted warfighters and professional security teams, the system operates completely without active RF or radar emissions, supporting autonomous standalone operation and networked regional surveillance.
It realizes non-line-of-sight (NLOS) early warning, 3D positioning and high-precision visual identification for various UAS threats including Class I/II/III drones and loitering munitions. Powered by embedded edge AI technology, the system completes full-link data processing locally. It meets military environmental standards, supports rapid field deployment, and provides persistent covert situational awareness for forward operating bases, border lines, coastal areas and critical infrastructures, covering military, law enforcement and civil security fields.
Traditional active detection equipment such as radar emits obvious electromagnetic signals, which are easy to be captured by enemy electronic surveillance systems and expose the deployment position. Conventional single passive sensors lack effective target verification means and cannot adapt to high-risk combat scenarios.
Most detection devices are restricted by line of sight, failing to work normally in urban canyons, dense foliage, fog, smoke and other environments. They cannot achieve stable detection of low, slow, small targets under NLOS conditions.
Large-scale detection equipment cannot be carried by individual soldiers. The deployment process is time-consuming and labor-intensive, which cannot meet the rapid maneuver and emergency layout demands of frontline mobile troops.
Traditional equipment lacks intelligent noise reduction and classification algorithms. It is prone to misjudge birds, wind noise and complex background interference as threats, bringing heavy operational burden to users. Meanwhile, most systems cannot resist electronic warfare jamming and fail in GPS-denied environments.
Single acoustic or optical sensors have performance limitations and cannot complement each other. Many devices adopt closed architecture, which is difficult to connect with the existing command and control (C2) system and unable to form a linked regional detection network.
The Bottom Line: The market urgently needs a portable, full-passive, all-weather acoustic-optical fusion C-UAS system, which features zero emission, strong anti-jamming, low false alarm, rapid deployment, edge autonomous computing and easy integration, to fully adapt to modern battlefield and multi-scenario security missions.
Built on dual-sensor fusion and edge AI architecture, Heimdall integrates acoustic detection, multi-spectrum optical monitoring, autonomous computing and network linkage capabilities to realize full-process intelligent detection and warning.
The 48-channel MEMS microphone array provides a 150° horizontal detection field of view. It conducts all-weather NLOS detection, accurately captures the acoustic characteristics of drones and loitering munitions, and calculates the 3D coordinates of targets to complete long-distance early warning.
The EO/IR tri-mode optical system supports panoramic visible light, telephoto zoom and infrared imaging, with a total fusion field of view of 130°. It automatically slews to the target according to acoustic positioning information, completes high-resolution visual verification, and realizes day-night continuous tracking.
Realizes linkage between acoustic and optical modules. Acoustics completes positioning and early warning under blocked line of sight, and optics conducts target confirmation and feature recording, making up for the defects of single sensor and improving overall detection reliability.
All target classification, noise filtering, trajectory calculation and threat judgment are completed by local edge computing, without relying on external servers or cloud. The embedded AI effectively filters background noise and maintains near-zero false alarm rate for mainstream UAS threats.
The whole system works in a fully passive mode with no electromagnetic radiation. It is immune to electronic warfare jamming and RF interference, and operates stably in GPS-denied environments to ensure the safety of operators and positions.
The whole machine weighs only 6.4kg with backpackable design. It complies with MIL-STD-810G/H military standards and IP65 protection. A single operator can finish vertical sector deployment within 2 minutes, adapting to mobile combat and patrol missions.
With an open modular architecture and standard C2 APIs, it supports TCP/IP, 4G/5G network transmission. Multiple devices can be networked to form a continuous detection chain, and stably push 3D telemetry data, threat alerts and image evidence to the superior command terminal.
The working temperature ranges from -30°C to 65°C. The acoustic module is not affected by fog, smoke and obstacles; the EO/IR dual-spectrum optical module adapts to day and night scenes, realizing all-time and all-weather persistent monitoring.
The innovative acoustic-optical slew-to-cue mechanism combines the NLOS advantage of acoustics and the high-precision identification advantage of optics. It achieves whole-link detection from long-distance early warning to close-range verification, and performs excellently in complex terrain such as cities, mountains and forests.
No radar, RF or electromagnetic signals are emitted during operation. It cannot be detected by enemy electronic reconnaissance equipment. It maintains absolute concealment in electronic warfare and GPS-denied scenarios, fundamentally avoiding position exposure risks.
Proprietary AI classifiers and noise reduction algorithms run locally, which can accurately distinguish drones, loitering munitions from organisms such as birds. The false alarm rate for Class I/II/III UAS is close to zero, greatly reducing the operator's workload. The system works independently offline with no network dependency.
The compact body (505mm×326mm×150mm) and 6.4kg lightweight design support individual backpack carrying. It passes MIL-STD-810G/H military environmental test and IP65 waterproof and dustproof protection, and adapts to harsh field environments such as high and low temperatures, wind and sand.
One-person rapid deployment within 2 minutes realizes flexible layout of sector defense. It is perfectly matched with the maneuvering characteristics of dismounted troops, patrol teams and mobile security forces, and can quickly build a covert early warning line in emergency situations.
Naturally resists electronic jamming and RF interference, and operates reliably in various complex electromagnetic environments. Acoustics plus EO/IR dual-spectrum optics realize all-weather and NLOS detection, free from the influence of weather, smoke and terrain obstacles.
The open modular design supports flexible expansion. Multiple units are networked to fill the blind areas of low-altitude radar in complex terrain. It is compatible with various existing command and control systems, realizing unified scheduling and data sharing of regional monitoring resources.
For typical targets, the acoustic detection range of Class III drones reaches 600m, the wide-angle visible light reaches 1400m, the infrared reaches 400m, and the telephoto visible light reaches 4000m; the acoustic detection range of loitering munitions such as Shahed 136 exceeds 5000m, fully covering the operational range of mainstream low-altitude threats.
