It is important for users to understand the direction and polarization of the EM field, and the
effect that antenna rotation will have on the above factors; this is beyond the scope of this
manual.
Press the Polarization button at the bottom of the screen to select between the three options
explained below:
•
Broadside is the typical configuration that most people use for reflection surveys. This
provides the best coupling between antennas and reduces reflections from targets off to
the side (Figure 6-25).
•
Endfire has the antennas in a line (Figure 6-26). This is sometimes used for larger
antennas where space is a consideration.
•
Cross-polarization orients one of the antennas (transmitter or receiver) 90 degrees with
respect to the other (Figure 6-27).
