SAR Satellite Imagery

Reliable intelligence in any weather, any time

Synthetic Aperture Radar (SAR) imagery provides consistent, high-resolution intelligence regardless of cloud, smoke, darkness or adverse weather. This makes SAR essential for defence, maritime, environmental and emergency operations where uninterrupted visibility is critical.

What SAR imagery delivers

SAR is ideal for persistent monitoring and applications where optical imagery is limited or unavailable

  • Maritime Surveillance

    Vessel detection, dark targets, anomaly detection

  • Flood Mapping & Environmental Monitoring

    Water extent, soil moisture, land cover change

  • Deformation & Movement Monitoring (InSAR)

    Subsidence, infrastructure stability, landslides

  • All-Weather Monitoring

    Cloud-prone, remote or inaccessible regions

  • Rapid, Time-critical Intelligence

    Day/Night Operations

When SAR Is the Best Choice

Choose SAR when:

  • You require coverage during cloud, storms, smoke, night-time or winter
  • You need to track vessels far offshore
  • You are assessing flood impacts or standing water
  • You require precise measurement of ground movement
  • You need highly reliable monitoring at regular intervals

If visual interpretation or colour-based classification is required, optical imagery may be a better fit.

SAR Constellations We Provide

Through our partners, we supply both new tasked collections and extensive archive coverage from leading radar systems:

  • Capella

    Capella operates a global, all‑weather X-band SAR constellation delivering very‑high‑resolution (down to 0.25 m) radar imagery with rapid, automated tasking and persistent coverage for mission‑critical monitoring.

  •
    Sentinel – 1A/1B/1C

    Sentinel‑1 is ESA’s all‑weather, day‑and‑night C‑band radar mission delivering frequent, reliable imagery for land, ocean, ice and emergency monitoring through a constellation of identical satellites.

  •
    TerraSAR-X and TanDEM-X (0.25m)

    TerraSAR‑X is a German X‑band SAR satellite delivering sub‑metre wide‑area, all‑weather InSAR compatible imagery with outstanding geometric accuracy as part of the Airbus radar constellation.

  •
    PAZ

    PAZ a Spanish X‑band SAR satellite, delivering high‑resolution all‑weather imagery and operating in constellation with TerraSAR‑X and TanDEM‑X to reduce revisit times.

  •
    Synspective Strix

    StriX is Synspective’s constellation of 100 kg class X band SAR satellites, delivering 1–3 m resolution, all weather imaging.

Orchard Management Using Satellite-Based Tree Health Detection

Geospatial Intelligence conducted a remote sensing assessment for an Australian orchard to identify unhealthy or damaged trees at scale. Using satellite imagery and NDVI analysis, the project produced a detailed tree health classification map, accuracy report, and geospatial outputs for operational use. The insights allow the orchard to detect issues earlier, improve decision making, and support long term productivity and orchard health.Continue reading→

Modelling Sea Level Rise and Storm Surge Risk for Coastal Resilience

Geospatial Intelligence conducted a sea level rise and storm surge modelling assessment for a coastal region comprising multiple cities. Using Earth Observation data, the analysis identified high-risk coastal zones and evaluated the potential impact of extreme storm surge scenarios. The insights enable local governments to strengthen emergency planning, protect critical infrastructure, and guide long-term climate adaptation strategies.Continue reading→
