In radar, what does Average Power (PAVG) refer to?

Average Power (PAVG) in radar systems refers to the measure of power delivered over an entire pulse repetition time (PRT). This average accounts for both the on-time (when the radar is actively transmitting signals) and off-time (when the radar is not transmitting) of the system. By integrating the total energy transmitted across the PRT and dividing it by the total time, one can get a consistent value that is indicative of the radar's performance over time.

This measure is crucial because it provides operators with a clear understanding of how much power is effectively being used for signal transmission over a given period, which directly influences the radar's detection capabilities and overall operational efficiency. It contrasts with measures like peak power, which only reflects the momentary energy during the pulse itself rather than the average energy output relevant for long-term performance analysis.
