Figure 1-6.—Duty cycle.
Since the duty cycle of a radar is usually known, the most common formula for average power is
expressed as:
Transposing the above formula gives us a common formula for peak power:
Peak power must be calculated more often than average power. This is because, as previously
mentioned, most measurement instruments measure average power directly. An example is shown below:
Where:
Before figuring Pp, you must figure duty cycle as follows:
Now that you have duty cycle, Pp may be calculated as follows: |
