Navigation General · Radar Controls
Excessive use of the sea clutter (STC) control is dangerous because it can:
- AIncrease the range scale automatically
- BSuppress weak echoes of small or close targets along with the clutter✓ Correct
- CDamage the antenna
- DReverse the heading flash
Explanation
STC reduces gain at short range to cut wave clutter, but turned up too far it will erase the echoes of small craft, buoys, or low targets near the ship. The control should be adjusted to break up clutter while leaving real targets visible.
