STC stands for which radar term?

• A. Signal Timing Control
• B. System Timing Control
• C. Sensitivity Time Control
• D. Sensor Timing Calibration

Answer: (C)

Sensitivity Time Control describes how a radar adjusts receiver sensitivity as time passes after a pulse is transmitted. The idea is to manage the receiver’s dynamic range: right after a pulse, echoes from nearby objects can be very strong and risk saturating the receiver or flooding it with clutter. By lowering the receiver gain in the early time window and then gradually increasing it for later times, the radar suppresses near-field clutter and preserves the ability to detect weaker, distant targets. This time-dependent gain control helps produce clearer, more usable returns across a range of distances. Other phrasing like Signal Timing Control, System Timing Control, or Sensor Timing Calibration aren’t the standard radar term for this concept; they would imply different timing or calibration ideas rather than the time-based adjustment of sensitivity that STC encapsulates.
