With a pulse-to-pulse coherent Doppler profiler, we can pick a specific remote region where we want the measurement to be made. Here we plan...

Here is a preliminary diagram of the prototype profiler that I plan to build. I intend to modify an existing depth transducer, replacing ...

It is possible to measure directly the lateral speed through water of a sailboat making leeway, by using a pulse-to-pulse coherent Doppler p...

This recent Sailing Anarchy entry about acoustic doppler velocimetry really got my attention, and I am thinking about developing a custom ...

Damping values is typically achieved by updating a running average of an appropriate number of past measurements.   But calculating averages...

Here is the code now used to calculate the measured apparent wind angle in this system. The analog-to-digital code makes use of the files ...

In the second post of this blog, I described a rather complicated method to calibrate the Raymarine ST60+ wind vane transducer. I have now ...
