Ship Tracking / Navy

The high-frequency over-the-horizon radar OTHR technology is well suited to protect the exclusive economic zone (EEZ). The unique beam-forming software of our OTHR system is the key component for the ship detection and tracking application to identify fishing pirates or smugglers far behind the horizon.

The low-noise non-interrupted FMcw mode of operation provides the best range/transmit-power performance on the OTHR market. This allows the operation with quite low power levels to get a range of up to 200 nautical miles.

The flexible data interface allows to use the provided ship tracks in multi-sensor networks.

In addition to that the OTHR data can be used for environmental protection applications, SAR or Tsunami Detection in parallel, making it a real dual use system.

Recommended Hardware Configurations 

for Ship Tracking / Navy

Tsunami Warning System
for ranges up to 200km                          


  • Each single WERA system can be used for Tsunami Detection
  • The array type antenna systems  ensure high performance and reliability
  • The fast real time processing on-site calculates the actual Tsunami probability
  • The detection range need to be adapted to the distance of the continental shelf edge
  • Best suited for 9 to 26MHz systems
