// Maple Shield - passive drone detection

Passive drone detection and airspace awareness for contested and remote environments.

Maple Shield is Maple Silicon Inc.'s passive drone detection system for contested and remote environments. It delivers zero-RF airspace awareness, is designed for distributed fixed-camera deployments, and uses CAIRN to turn passive video into operator-ready alerts at the edge.

// Platform signals
Positioning
Passive drone detection and operator-facing airspace awareness with zero RF emissions.
CAIRN
Architecture-level detection and intelligence designed for real-time edge deployment.
Deployment path
Designed for distributed fixed-camera infrastructure in remote and contested sites.
Scale advantage
Higher sensor density at a fraction of the cost of traditional systems.
Maturity
Prototype-stage system with current metrics still under validation.
Program signal
Submitted to NATO Innovation Continuum 2026 (IC26).
Availability
Open for evaluation conversations.

Early proof,
kept honest.

The credibility work here is simple: show the direction, show the doctrine relevance, and avoid pretending the product is further along than it is.

01 / NATO IC26
NATO submission note

Submitted to NATO Innovation Continuum 2026 as part of the current Maple Shield product direction.

02 / Edge bias
Zero-RF deployment

Positioned for passive sensing close to the sensor, without active RF emissions and without assuming a rich backend.

03 / Maturity
Prototype-stage system

Current metrics are still under validation. Evaluation conversations focus on deployment fit, density, and operational relevance rather than overstated maturity.


System performance
current targets.

Grouped the way an evaluator reads them: detection, performance, deployment, and reliability.

Detection
Coverage targets
  • 300-800 m for Class I UAS
  • Up to 1,500 m target for Class II
Performance
Real-time edge runtime
  • <50 ms end-to-end latency target
  • 30+ FPS on Jetson-class edge GPU hardware
Deployment
Node economics
  • <$1,000 CAD target cost per node
  • <25W power target per node
Reliability
Field conditions
  • <2% false positives with multi-frame validation
  • -40C to +50C target operating range with enclosure

These values are based on current prototype targets and ongoing validation. The goal is to keep claims grounded in measurable system behavior rather than theoretical capability.


CAIRN Detection
Engine

CAIRN combines real-time vision inference, multi-object tracking, and probabilistic risk scoring to identify and prioritize aerial threats under constrained edge environments. It is accelerated by the SparseFlow inference stack, enabling real-time performance on low-power edge hardware.

Layer 01
Perception Layer

Real-time vision inference tuned for passive drone and sUAS sensing on constrained edge hardware.

Layer 02
Tracking Layer

Multi-object drone and sUAS track continuity that preserves identity through clutter, motion, and partial occlusion.

Layer 03
Motion Intelligence Layer

Trajectory and movement interpretation for earlier recognition of approach vectors and threat behavior.

Layer 04
Risk Evaluation Layer

Probabilistic scoring that prioritizes persistence, directionality, and operationally relevant behavior.

Layer 05
Audit & Replay Layer

Replayable event evidence for operator review, debugging, and post-incident analysis.


Why Maple Shield wins
on deployment scale.

Maple Shield enables significantly higher sensor density at a fraction of the cost of traditional systems. The advantage is not just detecting drones. It is distributing more passive nodes across more space, with lower cost, lower infrastructure burden, and a cleaner path through fixed-camera deployments.

Higher sensor density

Low-cost passive nodes make it practical to field more sensing coverage than radar-heavy architectures and extend awareness across larger sites.

Passive and EMCON-compatible

No active RF emissions keeps Maple Shield aligned with EMCON-sensitive deployments where awareness matters but unnecessary signal exposure is unacceptable.

Fits fixed-camera deployments

Designed around distributed fixed-camera infrastructure so remote, Arctic, and critical-site coverage can scale without radar-heavy node economics.


Positioned against system
categories, not hype.

This is the category-level positioning Maple Shield is built around. The strongest advantage is deployment density: more passive nodes, distributed faster, at lower node cost.

System Cost per node Emissions Arctic capability EMCON compatibility Deployment speed Deployment density
Maple Shield <$1,000 CAD target None Targeted Native Fast High
Radar-heavy systems High Active Program dependent Limited Slower Low
RF-only systems Medium Passive Environment dependent Partial Fast Medium

Illustrative positioning only. Actual program fit depends on mission profile, terrain, and the wider sensor stack.


Operational scenarios that
make the value concrete.

Structured like operational notes instead of generic airspace language, so reviewers can see how the system would actually be evaluated.

01 / Forward operating base
EMCON scenario
  • Detection: 600 m quadcopter target
  • Latency: <50 ms target
  • RF emissions: none
  • Outcome: early warning without detection exposure
02 / Remote Arctic site
Low-infrastructure coverage
  • Detection: Class I UAS within current target range
  • Power: <25W per node target
  • Deployment: passive edge node on commercial hardware
  • Outcome: persistent awareness where logistics are thin
03 / Critical infrastructure
Distributed site coverage
  • Coverage: multi-node low-altitude monitoring
  • Cost: <$1,000 CAD per node target
  • Deployment density: significantly higher than traditional systems
  • Outcome: faster site coverage and cleaner operator escalation

Who Maple Shield
is for.

This is not a mass-market drone app. The product direction is shaped around operators and programs that care about passive sensing, auditability, and low-infrastructure deployment.

01 / Defence
Defence programs

Programs evaluating passive drone detection, airspace awareness, and operator-ready incident intelligence for sensitive environments.

02 / Infrastructure
Critical infrastructure operators

Energy, industrial, and other site operators that need persistent awareness and cleaner escalation around low-altitude aerial activity.

03 / Remote ops
Remote surveillance teams

Operators covering remote, border, maritime, or cold-weather locations where passive sensing and edge deployment matter more than cloud convenience.


// Evaluation path

Maple Shield should read like a serious passive-detection system.

The goal is not to oversell maturity. It is to make the category, doctrine fit, and deployment advantage clear enough that the right reviewer immediately understands why Maple Shield exists.

CAIRN is accelerated by the SparseFlow inference stack, enabling real-time performance on low-power edge hardware while Maple Shield stays focused on passive drone detection and operator-ready airspace awareness.
