What is the value of PW in the pulse range resolution formula?

The pulse range resolution formula is essential for understanding how radar systems differentiate between closely spaced targets. The value of PW, or pulse width, significantly impacts the ability of a radar system to distinguish between objects at a given distance.

In this context, the correct value of PW is expressed in feet. Pulse width is usually measured in a specific unit that allows for practical calculations in radar systems. Specifically, for range resolution, it is often stated that the range resolution is directly related to the pulse width, with a standard conversion indicating that a one-microsecond pulse width corresponds to a resolution of approximately 164 feet. This means that if your radar transmits a pulse that lasts one microsecond, it will have the capability of distinguishing two targets that are at least 164 feet apart.

Thus, understanding this measurement and its implications helps in interpreting how radar technology operates in distinguishing objects in a specified range.
