Mode identification in CIVA GWT

To do this, you have to go in the “Toolbox” (tab “View Options”) and untick the display of All modes with the same color. Then, assign a different color, and display the modes that contribute to the echo (as shown below).

 

 

In addition, the mode identification can also rely on other elements:

– The energy emission and sensitivity at reception data from the dispersion curves enable you to identify the modes that are actually sensitive in transmission and reception.

– For each of the strong modes, the time of flight from the probe to the reflector can be estimated with the energy velocity dispersion curve.
