Passive Detection · No Jamming · Canada-Compliant

Detect Drones Earlier. Suppress False Alarms. Cut Review Costs.

SkyGuard fuses RGB cameras, thermal infrared, acoustic spectra, mmWave radar, and RF metadata into one decision-support platform — designed to minimize false alarms and operator fatigue at a fraction of enterprise system costs.

The Challenge

Current Drone Detection Falls Short

Single-sensor systems produce too many false alarms. Enterprise solutions cost too much. And in Canada, active countermeasures are prohibited by law.

⚠️

False Alarms Drain Operators

Single-sensor systems confuse birds, aircraft, and clutter with drones — generating hundreds of false alerts per shift. Every wasted review wastes budget and erodes trust.

💰

Enterprise CUAS Is Unaffordable

Military-grade counter-UAV systems cost hundreds of thousands of dollars. Critical infrastructure operators — airports, utilities, prisons, events — need a lower-cost alternative.

🌙

No Single Sensor Is Enough

RGB cameras fail at night. Acoustic sensors are drowned out by wind. Radar struggles with small targets. RF is blind to RF-silent FPV drones. No single modality covers all scenarios.

⚖️

Jamming Is Illegal in Canada

ISED prohibits RF jamming devices without exemption. Any legitimate Canadian product must be passive — focused on detection, classification, alerting, and human review support only.

Sensor Fusion

Five Modalities. One Coherent Picture.

No single sensor covers every scenario. SkyGuard combines five complementary modalities and adapts weights dynamically to match operating conditions — day, night, rain, wind, or RF-silent threats.

Five sensor modalities — radar, acoustic, RF, thermal, and optical — streaming data to a single detection unit

RGB Camera

Primary visual detection & classification

Low cost, high resolution, color contextStruggles at night, in fog, and with small distant targets
🌡️

Thermal Infrared

Night & low-light tracking via heat contrast

Works in darkness; reveals heat signaturesHigher cost; thermal crossover at similar temperatures

Acoustic Spectrum

Low-cost rotor-sound cue

No line-of-sight required; very low costAffected by wind, traffic, and HVAC noise
📡

mmWave Radar

Range, velocity, and track continuity

Weather-independent; provides range/Doppler dataHigher cost; small RCS targets are challenging

Passive RF / Remote-ID

Protocol-presence metadata cue (receive-only)

Can identify actively transmitting dronesBlind to RF-silent FPV and autonomous drones
🔀

Confidence-Weighted Fusion

Each modality's weight adapts automatically — lower RGB weight at night, lower acoustic weight in high wind, higher radar weight when strong tracks exist. The system keeps working even when sensors are missing or unreliable.

Core Innovation

5-Layer False-Alarm Suppression

Most CUAS systems optimize for detection rate alone. SkyGuard treats false-alarm suppression as the primary engineering goal — because false alarms cost money, erode operator trust, and make systems unusable in practice.

01

Negative-Class Training

Birds, aircraft, insects, clouds, wires, and site-specific clutter are trained as explicit negative classes — not just absent positives.

02

Temporal Persistence

A detection on a single frame does not trigger an alert. Targets must persist across N-of-M frames or maintain track confidence above threshold.

03

Cross-Modal Confirmation

Alerts are promoted only when independent modalities agree — e.g., an RGB track corroborated by an acoustic drone-like spectrum or a radar velocity cue.

04

Contextual Plausibility

Speed, acceleration, trajectory smoothness, geofence zones, and approach direction filter implausible detections — while remaining robust to fast FPV drones.

05

Human-Review Triage

Three alert tiers: low-confidence events are logged silently; medium-confidence joins a review queue; high-confidence triggers an active alert — drastically reducing operator burden.

Development Roadmap

A Staged R&D Program

We follow a rigorous, evidence-based path from public dataset baselines to Canadian field validation — so every claim is backed by real measurements.

1Phase 1 · 4–6 weeks

Single-Modality Baselines

Establish honest per-sensor detection rates, false alarms per hour, and operational metrics on public datasets (Anti-UAV, DroneRF, MMAUD, Drone-vs-Bird).

2Phase 2 · 8–12 weeks

Canadian Field Dataset

Collect site-specific data: drones, birds, FPV targets, day/night/rain/snow, urban and industrial backgrounds, with certified pilots and privacy controls.

3Phase 3 · 4–6 weeks

Multimodal Fusion & Validation

Compare sensor combinations at a fixed 90% detection rate. Measure false alarms per hour, first-alert time, track continuity, and annualized cost per coverage area.

Use Cases

Built for Real Operational Environments

SkyGuard is designed for organizations that need affordable, reliable drone detection — not multi-million-dollar military platforms.

✈️

Airports & Airspace

Protect approach corridors and perimeters from unauthorized drone intrusions with 24/7 passive monitoring and low false-alarm rates.

Energy Infrastructure

Monitor pipelines, substations, and wind farms against drone surveillance and sabotage threats — day and night.

🏗️

Industrial Sites

Secure refineries, mines, and construction zones with scalable sensor configurations tailored to site budget and terrain.

🏟️

Public Events

Temporary deployments for stadiums, concerts, and government gatherings where drone intrusions create safety and security risks.

🏛️

Government Facilities

Border crossings, prisons, military support zones, and parliamentary precincts requiring compliant passive detection solutions.

🌲

Remote & Rural Monitoring

Low-cost RGB + acoustic configurations for sites where wired power and high-bandwidth connectivity are limited.

Honest Evaluation

We Measure What Actually Matters

mAP alone is insufficient for operational systems. A detector can score well on curated frames while still generating hundreds of false alarms per hour in continuous video. SkyGuard evaluates every sensor combination on operational metrics — at a fixed 90% detection rate, across real Canadian conditions.

Designed for Canadian Compliance from Day One

  • ISED-compliant: SkyGuard is strictly passive — no RF jamming, spoofing, or active countermeasures. All receive-only RF sensing uses only lawfully available spectrum data.
  • Transport Canada: Field data collection follows Canadian Aviation Regulations Part IX with certified pilots, site risk assessments, and airspace coordination.
  • PIPEDA / Privacy: Audio is processed as spectrograms or extracted features — raw audio is not stored. Camera coverage is scoped to minimize capture of private spaces.
  • IDEaS-aligned: Research approach is consistent with Canada's IDEaS Counter-UAS challenge, which funded passive multi-sensor and acoustic detection concepts.
