What type of radar transmitter power is measured over a period of time?

Average power is the correct choice because it refers to the total amount of energy transmitted over a specific time interval, taking into account the varying power levels during that period. In radar systems, the transmitter does not always operate at a constant power level due to the nature of the signal modulation and pulse characteristics. Average power is calculated by integrating the instantaneous power over the pulse duration and dividing by that duration, providing a consistent measure that reflects the effective power output over time.

Understanding average power is critical in radar applications, as it affects the radar's performance capabilities, including detection ranges and clarity of signals. This distinction helps in charting the overall effectiveness of the radar system while ensuring proper power supply and system design align with operational needs.
