In STC tuning, Rough controls require what?

Explanation:
STC tuning controls how receiver gain changes with range to keep clutter from overwhelming the radar signal. When you have rough returns—in other words, strong, jagged near-range clutter—the echoes at short distances are much more intense and variable. To prevent receiver overload and to preserve the ability to see farther targets, you must apply more attenuation to the near-range part of the return. That’s why rough controls require more attenuation. In calmer conditions, near-range echoes are weaker, so less attenuation is needed.
