WaveFinder is a stand-alone sensor specifically designed for motion-compensated wave monitoring. The sensor provides accurate measurements undisturbed by fog, rain and water spray (unlike laser sensors). WaveFinder is also available as an IoT-based sensor, meaning that it is truly plug-and-play, only needing power and an Internet connection to give secure access to immediate, real-time data about the ocean state.
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
How Does It Work?
WaveFinder is a microwave radar that functions by sending microwave frequency-modulated (FM) chirp signals and receiving the echo from the water surface.
The round-trip 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 measures with millimetre accuracy (+/- 1mm) in all weather conditions. Delivered with motion compensation as standard, it is the only system in the world which provides wave parameter data with sufficient accuracy to meet DNV GL’s Offshore Standard (DNV-OS-H101: Marine Operations, General).
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. WaveFinder is a decision-support solution which provides all stakeholder with access to real-time data, anytime, anywhere.

NOAA’s Center for Operational Oceanographic Products and Services (CO-OPS) conducted a 3-month field study comparing radar-based water level sensors. They found that the Miros RangeFinder is the optimal choice for wave measurements.
Miros is using a RangeFinder to measure the height, length and period of the waves at Flaskebekk, a small community on the water’s edge, deep within the Oslofjord. We hope to contribute to a better understanding of the “mini-tsunamis” occurring there, what causes them, and their potential impacts.
Marine operations are particularly sensitive to environmental challenges such as those posed by unpredictable weather conditions. Undertaking real-time measurements and analysis, as well as forming appropriate risk assessments based on wind and weather data, can help to mitigate the potential challenges of project delays, cost overruns, property damage and safety.
