Normally, the reflected echoes from long range targets appear on the display as
weaker and smaller blips even though they are compensated by the radars internal
circuitry. The echo stretch function magnifies these small blips in all ranges. Two
types of echo stretch are available: LOW which stretches echoes in bearing direction
and HIGH which stretches them in both range and bearing directions.
This function magnifies not only targets but also sea clutter and radar interference.
For this reason, be sure sea clutter and radar interference are properly suppressed
before activating the echo stretch.
