What effect does shorter pulse width have on radar resolution?

Shorter pulse width significantly enhances radar range resolution because range resolution refers to the system's ability to distinguish between two closely spaced objects in the direction of the radar beam. When the pulse width is shorter, the radar sends out a briefer signal, allowing for a more precise determination of the distance to objects located close together. This improved ability to differentiate between targets means that radar can provide clearer and more accurate information regarding multiple objects in a particular area, especially in complex environments.

In contrast, longer pulse widths can lead to overlap in the return signals from targets, making it challenging to distinguish them as separate entities. Therefore, when it comes to radar functionality, having a shorter pulse width is critical for achieving higher resolution and more detailed analyses of the environment being monitored.
