Sensitivity Time Control
Encyclopedia
Sensitivity Time Control (STC) is used to attenuate the very strong signals returned from nearby ground clutter targets in the first few range gates of a Radar
receiver. Without this signal attenuation
, the receiver would routinely saturate due to the strong signals.
Radar
Radar is an object-detection system which uses radio waves to determine the range, altitude, direction, or speed of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. The radar dish or antenna transmits pulses of radio...

Attenuation
In physics, attenuation is the gradual loss in intensity of any kind of flux through a medium. For instance, sunlight is attenuated by dark glasses, X-rays are attenuated by lead, and light and sound are attenuated by water.In electrical engineering and telecommunications, attenuation affects the...
