How does pulse shape affect radar functionality?

The shape of the radar pulse plays a crucial role in the radar's functionality, particularly in determining the system's minimum and maximum operational range as well as its accuracy.

Pulse shape affects how the radar signal propagates and interacts with objects. A well-defined pulse shape allows for clearer differentiation between the transmitted signal and the echoes received from targets. It influences the time resolution of the radar, which is essentially the ability to distinguish between two closely spaced objects. A sharp pulse shape can enhance the system’s capability to identify targets more precisely and at greater distances.

In addition, the pulse width—the duration of the radar pulse—can impact the radar's minimum range. A shorter pulse width generally results in a shorter minimum range, as the radar can more accurately detect the return signal close to the transmitter. Conversely, longer pulses may provide better energy on target but can reduce the radar's ability to discern closely spaced objects.

Thus, the pulse shape significantly affects both the operational range and the accuracy of radar systems, making this the correct choice in relation to how pulse shape impacts radar functionality.
