
Δ: Overall beam positional stability

Δx: Beam positional stability in the azimuth direction.

Δy: Beam positional stability perpendicularly to the azimuth.

RMS : RMS standard deviation value of the centroid’s position (not ISO measure)
The beam positional stability values are based on the standard deviation concept
3
. Small values
represent small deviations and a good stability.
Please refer to ANNEXE A (p.58) for ISO mathematical definitions of the quantities listed above.
6.4.1. Beam Tracking Display: Controls
The toolbar buttons on the upper right corner control the beam tracking plot.
Save: Saves all the centroid coordinates available in the buffer in a .TXT file.
Print Screen: Saves a .bmp image of the current beam tracking display.
Reset Buffer: Erases all the data from the buffer and clears the chart.
Zoom: Activates the zoom. Zooming can be done by selecting an area with the left mouse button
and de-zooming can be done by double-clicking the image.
Set Origin Point: Sets the origin point (0, 0) of the sensor for the relative positioning, Please refer
to section 4.5.4.2.
