For more than 35 years, Miros has provided accurate, reliable ocean-monitoring systems to the maritime industry. Our expertise lies in measuring local environmental conditions and making the data accessible in real time, on- or offshore.
Wavex is a dry sensor that leverages X-band navigation radar technology for surface current measurements. The sensor delivers highly accurate real-time data undisturbed by air bubbles, turbulence or other interferences caused by vessel motion. Wavex does away with the time- and cost-related challenges of installing and maintaining underwater equipment and can be interfaced with existing marine X-band radar without any need for calibration.
Miros Wavex Applications & Benefits
Wavex provides accurate and reliable wave parameters, including 2D-spectrum, surface current magnitude and direction, as well as speed through water calculations – all these output parameters are key to:
Speed optimisation to save fuel
Enhanced hull and propeller performance management
Reduced cost and risk due to weather claims
Reduced weather-related vessel and cargo damage
Improved passenger comfort
Miros’ Wavex technology provides you with accurate, real-time ocean surface current measurements uninfluenced by vessel motion and propellers while doing away with the costs of traditional underwater sensors and the related maintenance and underwater operations.
How Does It Work?
The Wavex system measures sea state from digitised sea clutter images provided by a marine X-band radar. The radar backscatter from the sea surface is modulated by gravity waves, giving wave-like patterns in the images. The modulation is related to three mechanisms:
- Tilt modulation
- Hydrodynamic modulation
Grazing angles in the range of 1 to 10 degrees are recommended to achieve an appropriate radar image contrast Cartesian sections are extracted from the radar images for further processing and data from the Cartesian sections are combined into one directional wave spectrum. A minimum wind speed of 1 – 2 m/s must be present for Wavex to record wave a and current data. Recommended radar antenna mounting height is 15 – 100 meters above the sea.
