SAR Drone ─ Radio Direction Finder

SAR Radio Detection Finder compatible with multiple SAR Drone platforms 

Because in today’s world, almost everyone carries at least one wireless wearable device that frequently transmits signals.

SAR Drone ► Radio Direction Finder (RDF)

Because in today’s world, almost everyone carries at least one wireless wearable device that frequently transmits signals.

By integrating the X•SAR Radio Direction Finder, a (Search and Rescue) SAR drone can detect and locate signals from nearby devices — whether transmitted via Wi-Fi, Bluetooth, Cellular Devices (2G, 4G, 5G), or RF Emergency Locator Beacons — helping teams quickly identify and locate missing persons even in challenging environments.

Because in today’s world, almost everyone carries at least one wireless wearable device that frequently transmits signals.

The X•SAR Drone is developed as an add-on for SAR drone cameras, this system minimizes blind spots and greatly enhances situational awareness during search and rescue missions.

Various methods of deploying the X•SAR Drone ─ Radio Direction Finder

1)   Long-Range Radio Direction Finding (RDF) ►►

  • In this mode, the system utilizes forward-facing directional antennas (►►) to measure the signal strength of preset frequencies within a focused 45°–90° field of view.   This configuration enhances directional situational awareness, allowing operators to pinpoint signal sources more precisely over long distances.

2)   Short-Range Radio Direction Finder (RDF) ▼▼

  • In this mode, the system employs downward-facing directional antennas (▼▼) to measure signal strength across preset frequencies within a focused 45° field of view.   This configuration enables operators to fly systematic search lines over the ground, scanning for wireless signals emitted by lost persons’ wearables, beacons, or mobile phones — effectively locating the area of highest signal strength.

3)   Short-Range Radio Detection Finder (BLE + Wi-Fi) ▼▼

  • The system passively detects wireless wearables and mobile devices, capturing attributes such as the device name (e.g., “Jean’s iPhone”) to enhance situational awareness and confirmation.   In this mode, the system employs downward-facing directional antennas (▼▼) to scan a focused 45° to 60° field of view while flying systematic search lines over the ground.
