Why EchoNet Complements Existing Systems
Existing CUAS architectures have well-defined coverage gaps. EchoNet is designed to operate exactly where each conventional layer reaches its limits.
Ground clutter and low-altitude blind zones
Radar performance degrades against low, slow, small targets due to ground clutter and beam geometry. Hostile UAS increasingly exploit this by flying intentionally low to evade radar coverage. EchoNet's acoustic layer does not depend on reflected signals; it operates effectively where radar return is unreliable.
RF-silent and tethered platforms are invisible
Conventional RF detection is completely blind to RF-silent UAS: fibre-tethered, autonomous, and pre-programmed platforms emit no RF signature to detect. No amount of RF sensitivity closes this gap. EchoNet's acoustic and thermal layers detect physical presence regardless of emission state.
Line-of-sight and lighting dependencies
EO/IR sensors require unobstructed line of sight, adequate lighting, and precise aiming; they cannot search, only confirm. Without directional cueing from another sensor, EO/IR coverage is extremely narrow. EchoNet operates day and night, through terrain masking and adverse weather, with omnidirectional acoustic coverage per node.
Centralized sensors are single points of failure
High-value centralized sensors are high-value targets. Jamming, spoofing, or physical neutralization of one node degrades entire coverage zones. EchoNet's distributed mesh maintains coverage under partial node loss.
Sensing Architecture
Three passive modalities. One intelligent fusion layer.
What the Fusion Layer Sees
Threat type is determined by which modalities agree, and which don't.
Fusion logic reduces false alarms and identifies threat class, especially RF-silent low-altitude threats that RF-only systems cannot see.
Where EchoNet Fits
EchoNet is not a radar replacement. It is the persistent passive layer that fills the gap radar cannot see, and then cues the systems that can respond.
Integration & Interoperability
EchoNet is not a closed system. The architecture prioritizes integration readiness at every layer, from sensor output to command interface, ensuring compatibility with existing and future operational frameworks.
Architecture-ready for integration with external C2 systems. Not a standalone endpoint: a distributed sensing extension designed to feed into existing operational data flows.
Network outputs are structured for downstream consumption by command and control platforms. Data formats are designed with interoperability as a primary architectural constraint.
Architecture designed for compatibility with digital C2 data flow standards including CoT and SAPIENT-type message structures. Integration pathways do not require modification of upstream systems.
An API-based data layer enables modular connection to external processing, display, and decision-support systems without requiring proprietary middleware.
EchoNet is architected as a complementary sensing layer. Deployment augments existing sensor coverage without requiring replacement or reconfiguration of installed systems.
Maturity & Path Forward
EchoNet components are at TRL 5; system-level integration targets TRL 6 at the 2026 Sandbox. The following reflects an accurate account of what has been validated, what is under active refinement, and what will be tested at Suffield.
