The ratio of the Pulse Width (PW) to Pulse Repetition Interval (PRI) expressed in percent is referred to as which term?

The term that describes the ratio of the Pulse Width (PW) to the Pulse Repetition Interval (PRI), expressed as a percentage, is known as the Duty Cycle. This concept is crucial in electronic warfare and radar systems as it provides insight into how effectively a system can transmit and receive signals.

The Duty Cycle is calculated by taking the Pulse Width, which is the duration of the pulse, and dividing it by the Pulse Repetition Interval, the total time between the start of one pulse and the start of the next. This ratio tells us how much of the time a system is actively transmitting versus being idle. A higher Duty Cycle indicates that the system is transmitting more frequently, which can be beneficial for signal clarity and detection, but may also lead to increased power consumption and thermal load.

Understanding Duty Cycle is essential for optimizing electronic warfare systems in terms of range, detection capabilities, and resource management. This makes it a fundamental concept within the study of radar and electronic warfare technologies.
