What is the average power if the RADAR set has a PRF of 1000 Hz and a peak power rating of 100 kilowatts?

To determine the average power of a radar set, knowing the pulse repetition frequency (PRF) and the peak power is essential. The average power can be calculated using the formula:

Average Power = Peak Power × Duty Cycle

The duty cycle represents the proportion of time the radar is transmitting signals compared to the total time interval, which can be calculated from the PRF and the pulse width. The relationship between PRF, pulse width, and duty cycle is crucial.

In this scenario, if the PRF is 1000 Hz, this means the radar emits 1000 pulses per second. Assuming that each pulse has a certain duration, one needs to conduct the calculation based on typical radar setups. For a typical radar signal, let's assume a pulse width of 1 millisecond (0.001 seconds). This leads to:

Duty Cycle = Pulse Width / Pulse Period

Where Pulse Period = 1 / PRF = 1 / 1000 seconds = 0.001 seconds.

Thus, the duty cycle in this case would be:

Duty Cycle = 0.001 seconds / 0.001 seconds = 1.

This implies that all the time is accounted for with the radar actively transmitting. However, typically the pulse width is
