Helzel Messtechnik GmbH founded in 1995, specialises in the development and production of environmental and oceanographic measurement systems.
Helzel Messtechnik provides all services and training to configure the HF radar systems and software according to the operational requirements.
The HELZEL High-Frequency Over-the-Horizon Radar (OTHR) delivers reliable ship detection and tracking far beyond the horizon—dramatically enhancing maritime situational awareness where it matters most.
Monitor your Exclusive Economic Zone (EEZ) with confidence and gain a decisive advantage in maritime security, border protection, and sovereign surveillance.
Powered by high-speed, precision beamforming, HELZEL OTHR integrates automatic self-calibration and advanced frequency-hopping technology to ensure robust, resilient performance in demanding operational environments.
Its low-noise, continuous FMCW operation sets a new benchmark for range and power efficiency. Operating at low transmit power (<1000 W EIRP), the system achieves detection ranges of up to 200 nautical miles, reducing infrastructure demands while maximizing coverage.
Beyond surveillance, HELZEL OTHR can also deliver valuable oceanographic insights—including sea-surface current measurements—supporting drift prediction, Search & Rescue operations, and maritime safety, depending on site conditions.
The HELZEL high-frequency Over-the-Horizon Radar (OTHR) is designed for ship detection and tracking beyond the horizon, it significantly enhances maritime situational awareness.
Monitor your Exclusive Economic Zone (EEZ) with confidence and gain a strategic edge in maritime security.
The HELZEL OTHR combines fast and precise beamforming algorithms with automatic self-calibration and advanced frequency-hopping technology.
The low-noise, continuous FMCW operation ensures best-in-class range and power efficiency, allowing operation at very low power levels (<1000 W EIRP) while achieving detection ranges of up to 200 nautical miles.
Depending on site conditions, HELZEL OTHR systems can also provide valuable oceanographic data—such as sea-surface currents—to support drift prediction, Search & Rescue operations.
