Omni beam

When the Omni beam is tilted, the total beam picture can be
compared with folding an umbrella, which means that all beams
in 360 degrees around the vessel have the same tilt angle.
Figure 2 Omni beam principle
The beam can be tilted from +10 up to -60 degrees down.
In addition to seeing the target from above, it is also possible
to see the target from the side, by using the vertical slice
presentation. In this case the beam covers a continuous vertical
beam from 0 to -60 degrees in one transmission.
