Coherent Change Detection (CCD) technology provides a powerful tool for identifying even the most subtle changes in terrain, infrastructure, or activity—with pixel-level accuracy. Built on the foundation of IMSAR’s high-resolution Synthetic Aperture Radar (SAR) imaging, CCD enhances situational awareness across defense, security, and commercial sectors.

What Is Coherent Change Detection?

CCD works by comparing two or more SAR images taken over the same geographic area at different times. By analyzing phase coherence, IMSAR’s CCD algorithms detect real changes—such as vehicle movement, construction, land shifts, or tampering—while filtering out false positives caused by environmental factors.

Key Benefits of IMSAR CCD

All-Weather, Day/Night Operation

Process and interpret data in near real-time for fast decision-making.

Minimal False Alarms

Minimal False Alarms

IMSAR’s refined CCD analytics distinguish real-world activity from noise and natural variation.

Applications of CCD Technology

IMSAR’s CCD solutions are used in a variety of mission-critical operations:

  • Military and Intelligence Monitoring

    Detect construction of enemy fortifications, hidden activity, and equipment movement.

  • Border and Perimeter Security

    Identify fence breaches, tampering, and illicit crossings.

  • Disaster Response and Recovery

    Assess infrastructure damage, land displacement, and flood effects.

  • Infrastructure and Asset Protection

    Monitor pipelines, power grids, and sensitive facilities for unauthorized changes.

  • Environmental and Geological Monitoring

    Track erosion, landslides, and other landscape transformations over time.
