It refers to the process of controlling the flow of signals based on certain conditions or criteria.
Gating is used to control the transmission and reception of radar pulses, allowing the system to focus on specific ranges or angles of interest while ignoring other signals.
This helps improve target detection and reduces interference from unwanted reflections.
Gating is used to synchronize the data acquisition process with the patient's respiratory or cardiac cycle.
The specific method used depends on the application requirements and the characteristics of the signals being processed.
