Note
On the RAT, F1 - F3 and F5 - F7 are not used.
Sonar Gain (C1, C4)
This sets the sonar receive gain as required - typically
this is around 20% but can be varied according to
water and target conditions.
Contrast (C2, C5)
This sets the display contrast between hard and soft
targets. It can help to find small features in a generally
featureless situation or exclude clutter from a heavily
featured seabed.
Range (C3)
This sets the maximum range the sonar will scan.
Long ranges are scanned more slowly than short
ranges due to the limit imposed by the velocity of
sound in water (and may require a slower vehicle
speed if the the Sidescan is being towed).
Resolution (F4)
Resolution toggles through 4 preset sampling periods
over the pulsed range.
Lo
resolution produces the least samples and gives the
lowest resolution. The number of samples is increased
from
Med
,
Hi
through to
Ult
. Usually a Lo or
Med resolution are used for very fast tow speeds
where more scan-line updates are required giving
coarser detail. Hi or Ult should be used for detailed
examination of targets at a slower tow-speed.
Frequency
On the sidescan sonars this is for information only and
cannot be changed.
