1.23 Echo Stretch
The echo stretch feature enlarges targets in the range and bearing directions to make
them easier to see, and it is available on any range. There are three types of echo
stretch, 1, 2 and 3, and the higher the number the greater the amount of stretch.
Note: The echo stretch magnifies not only small target pips but also returns (clutter)
from sea surface, rain and radar interference. For this reason, make sure these types
of interference have been sufficiently reduced before activating the echo stretch.
You can access this feature from the InstantAccess bar
™
, or from the menu. The avail-
able options are: [OFF], [1], [2] or [3].
