Miros delivers world-class class remote sensors for measuring the ocean surface. Our portfolio of sensors is unique in its accuracy and availability providing out-of-water sea state measurements, free from structural disturbances. Miros Group has a 30-year track record of successfully providing ocean insights to the global maritime industry, on and off-shore.


The Miros WaveFinder is a dry, microwave radar sensor for measurements of wave height, wave period, water level, draught, air gap and motion and is suitable for a wide variety of applications. The instrument is the only DNV GL – certified product on the market for alpha-factor related wave monitoring.

How does it work?

The WaveFinder is a microwave radar sending microwave frequency-modulated (FM) chirp signals and receiving the echo from the water surface. The roundtrip delay in signal propagation between the antenna and the water surface causes a beat-signal in the receiver. The beat frequency is then converted to an accurate distance. The distance to the surface can range from 1 to 100 meters which is superior to what competing sensors can offer. Up to 50 measurements per second are averaged over a user-selectable averaging time. Therefore, the WaveFinder gives uniquely accurate range measurements and high long-term stability.

What makes the WaveFinder unique?

WaveFinder is the only system to meet the accuracy requirements of DNV GL’s Offshore Standard. It measures with +/- 1-millimetre accuracy in all weather conditions.

The WaveFinder system is delivered with an internal motion compensation unit (MRU – Motion Reference Unit) for measurements on vessels.

The Miros WaveFinder offers the following benefits:

  • Operability improvements up to 15%*
  • Increased operational safety
  • Real-time data delivered to any device
  • Historical weather data available to all stakeholders offshore and onshore

The value of the Miros WaveFinder lies in increased situational awareness through high-accuracy and high-availability sea state data. This translates into wider weather windows, increased performance within the weather window and increased safety from accurate, real-time wave data. The WaveFinder is a decision-support solution which provides all stakeholder with access to real-time data, anytime, anywhere.
