5.2.5 Video Emphasis
Strong video signals can be accentuated optically
by switching on the Video Emphasis function.
Video Emphasis can be used to increase the
detection of targets of the radar. Very strong
echoes will be shown in light green colour. It can
help to decide whether an echo is one or two
combined objects or whether a strong object is
covered by noise, for example the echo of a cloud.
The display of targets on the PPI will be improved,
targets will not get lost if VE is switched off. Also
structures in land areas or in rainclouds or
seaclutter can be made more visible by the VE
function, for instance a light house on a land area
or buoys with only a short distance to the land,
whose echoes would normally melt into the ones of
the land.
The examples show a radar echo that is covered by
the noise of a raincloud.
5.2.6 Hide Video / Overlay
The radar video itself or the superimposed synthetics overlay can
be suppressed temporarily by holding down the appropriate push-
buttons. As soon as the pushbuttons are released, the video or
the synthetic overlay are displayed again.
