The time elapsing in microseconds between the start of one pulse and the start of the next is known as which term?

• A. Pulse Repetition Frequency (PRF)
• B. Pulse Repetition Interval (PRI)
• C. Rest Time
• D. Pulse Width (PW)

Answer: (B)

The term that describes the time elapsing in microseconds between the start of one pulse and the start of the next is known as the Pulse Repetition Interval (PRI). This interval is a critical metric in radar and communication systems, as it directly influences the system's ability to detect and process returning signals. Understanding PRI is essential for determining how frequently the system issues pulses, which can affect its resolution and detection capabilities. In contrast, Pulse Repetition Frequency (PRF) refers to the number of pulses transmitted in one second, which is the inverse of the PRI. Rest Time is not a standard term used in the context of pulse timing, and Pulse Width (PW) describes the duration of an individual pulse, rather than the time between pulses. These distinctions are important for comprehending how various timing parameters interact in electronic warfare and radar systems.
