INSAR FOR DEFENSE AND SECURITY

Implementing InSAR satellite services in security and defense offers powerful capabilities for early detection and risk assessment of ground movements that could threaten critical infrastructure, borders, or military assets. By providing millimeter-level precision in monitoring terrain stability, InSAR enables defense organizations to detect subsidence, tunneling, or structural shifts around sensitive facilities and strategic zones. Continuous, all-weather monitoring enhances situational awareness and operational readiness, supporting both preventive intelligence and rapid response in dynamic or remote environments.

​

 

BORDER & PERIMETER SURVEILLANCE

 

 

Detect subtle ground disturbances caused by tunneling, underground storage, vehicle buildup or troop movement near borders (e.g. using sewer system). Especially relevant for monitoring long, remote borders where physical patrol is costly.

​

​

​

MILITARY BASE & AIRFIELD SECURITY

 

 

 

 

Monitor runways, hangars, ammunition depots, or radar installations for ground shifts that could compromise operations. Detect possible sabotage or underground infiltration attempts.

​

EARLY WARNING FOR STRATEGIC INFRASTRUCTURE

 

 

 

Nuclear plants, military communications stations, fuel depots: deformation tracking can provide early warnings of structural instability.

​

​

​

POST-STRIKE  DAMAGE ASSESSMENT

 

 

After missile/artillery strikes, InSAR can detect ground and structural shifts not visible in optical imagery (e.g., hidden subsidence, collapsed underground bunkers). Could help identify hidden secondary damage.

TECHNOLOGY LIMITATIONS

​

​

1.DATA LATENCY

 

InSAR requires multiple satellite passes (hours → days) before usable change maps are generated.

 

In fast-moving defense operations, this can be “too slow” compared to drones or real-time sensors. Commercial satellite data is needed to mitigate this.

​​

 

2.  WEATHER & ENVIRONMENTAL FACTORS

 

Radar is generally all-weather, but coherence drops in vegetation, snow, or deserts. That reduces accuracy in some military terrains.

​​

 

3. RESOLUTION LIMITATIONS

 

Most InSAR data is very good for large-area monitoring (mm precision over km²), but fine-scale tactical needs (e.g., spotting a small tunnel entrance or camouflaged military asset) might need complementary sensors or verification methods.

​

 

4. FALSE POSITIVES / SIGNAL NOISE

 

Military environments have explosions, vehicle traffic, and dynamic terrain changes that might trigger false deformation signals.​​​​

 

 

 

INSAR IS BEST USED AS A COMPLEMENTARY TOOL FOR WIDE-AREA PERSISTENT MONITORING, NOT TACTICAL OPS. COLLABORATION WITH MULTIPLE COMMERCIAL SATELLITE DATA PROVIDERS ⟶ REDUCE LATENCY.

ML FILTERING + FUSION WITH OPTICAL/UAV DATA, FUSION WITH GEOTECHNICAL DATA AS NEEDED.
