PLAY
2.1

Principle of Measurement

This software analyzes sea waves by using the received radar signal. When observing the waves
with the radar, sea clutter echoes appear as stripes.
The amplitude of the sea reflection echo depends on the roughness caused by the wind acting on
the sea reflection. (It is not the height of the wave.) This software obtains multiple echoes, pro-
cesses the data, and calculates the wave spectrum, wave height, wave direction, and wave peri-
od.
2.2

Reliability of Analysis Results

When the sea reflection echoes are displayed with stripes, the analysis results are more reliable.
When the sea reflection echoes are not displayed in stripes (lull, rain), the analysis results are less
reliable.
