How can the pulse width influence radar performance?

The influence of pulse width on radar performance is primarily linked to its role in determining range accuracy and the minimum range at which a radar system can effectively detect targets. A radar system sends out pulses of electromagnetic energy, and the duration of these pulses (pulse width) plays a crucial role in how accurately the system can measure the distance to a target.

When the pulse width is shorter, it allows for a more accurate determination of range because the system can process more time resolution in measuring the time it takes for the pulse to travel to the target and back. This means the radar can identify objects much closer to the radar site without the risk of ambiguity or confusion over returned signals, enhancing overall accuracy. Conversely, a longer pulse width can lead to decreased range resolution, making it challenging to distinguish between closely spaced targets.

Thus, the relationship between pulse width and range accuracy directly affects radar performance, particularly in applications requiring precision and the ability to operate effectively at short distances.
