UAV-SAR Landmine Detection

Give the land
back.

Tsunagi develops UAV-mounted synthetic aperture radar to detect buried landmines from the air—before people enter hazardous ground.

01 / Technology

Core technology

See what is underground.

We use radar—not hands—to find landmines. The UAV scans large areas from the air before anyone enters contaminated ground.

Synthetic Aperture Radar

Mounted on an autonomous UAV, the radar surveys the ground without physical contact and turns subsurface measurements into actionable survey data.

  • Wide-area subsurface sensing from the air
  • Operates in dense vegetation and difficult terrain
  • Keeps operators away from hazardous zones
  • AI-assisted anomaly prioritization
  • Data packages for demining operators

02 / Applications

Applications

Where we operate.

From humanitarian operations to security applications, the system is designed for difficult terrain and hazardous environments.

01

Humanitarian mine clearance

Post-conflict survey in Southeast Asia, Africa, and Eastern Europe. Accelerating the safe return of agricultural and civilian land.

02

UXO & ERW survey

Surveying for unexploded ordnance beyond anti-personnel mines, including artillery shells and cluster munitions.

03

Border & perimeter security

Rapid subsurface anomaly screening along borders and around critical infrastructure.

03 / Process

Operational process

How it works.

A repeatable four-step workflow from flight planning to the final survey report.

01

UAV-SAR wide-area survey

Autonomous UAV flights cover the target zone, collecting radar data with precise GNSS positioning.

02

AI-assisted anomaly detection

The processing pipeline analyzes subsurface data and produces a prioritized map of suspect areas.

03

Ground confirmation

Ground teams inspect only flagged locations, reducing the area that requires manual investigation.

04

Survey report

A complete data package is delivered to demining operators and partner organizations.
