Maritime Monitoring and Grey-Zone Activity Detection
Naval ISR for littoral, coastal, and congested sea lanes — closing detection gaps left by AIS-disabled vessels, persistent haze, and rapidly fading wakes.
Where visible-light sensors lose contact
Grey-zone maritime operations exploit AIS gaps, fading wakes, and haze degradation. SWIR closes those gaps by reading materials, not just light.
Three blind spots in visible-spectrum maritime ISR
Wakes dissipate fast, AIS goes silent, and haze degrades imagery — leaving commanders without confident attribution or intent assessment in the most contested waters.
Wakes dissipate into background noise once a vessel slows, manoeuvres, or exits the area — limiting confidence in detection and behavioural analysis.
Grey-zone activity often takes place in marine humidity and aerosols where visible-spectrum detection is compromised.
AIS-disabled, spoofed, or intermittent transmitters defeat cooperative identification; RF SIGINT and SAR indicate presence but lack surface-level confirmation.
SAR and RF detect presence — SWIR confirms behaviour
SWIR fuses with SAR and RF SIGINT to provide visual and behavioural confirmation, closing critical gaps in non-cooperative maritime monitoring.
SWIR highlights wake patterns long after they fade from visible imagery, supporting loitering detection and intent assessment.
Short-Wave Infrared sensing operates through coastal humidity and sea mist, preserving detection when visible bands fail.
Material reflectance differences distinguish vessel hulls from background clutter, enabling earlier detection of low-profile, non-cooperative vessels.
From presence to behaviour
SWIR strengthens the fusion of RF, SAR, and surface intelligence — turning fragmentary detections into confident attribution.
Track vessel movement and behaviour after the wake has visually dissipated — supporting loitering detection and intent assessment.
Confirm presence and intent for vessels with AIS disabled, spoofed, or intermittent — closing gaps in non-cooperative maritime monitoring.
SWIR penetrates marine aerosols and humidity, preserving maritime ISR continuity in conditions that defeat visible sensors.
