Sensitivity Time Control suppresses returns from which part of the range?

Explanation:
Sensitivity Time Control lowers the receiver gain for the early part of the range to cut down on near-field clutter, such as sea clutter, and then gradually returns to normal as range increases. This targeted suppression means echoes from the inner ranges are reduced, while echoes from farther ranges can be seen clearly because the gain has recovered by the time those ranges are scanned. Therefore, returns from the inner ranges are the ones that are suppressed. Outer ranges are not suppressed to the same extent, and STC doesn’t blanketly suppress all ranges.
