When is a short pulse width most beneficial in a RADAR system?

A short pulse width in a RADAR system is most beneficial when detecting fast-moving targets due to its ability to provide higher resolution in measurements. This high resolution is crucial because fast-moving targets can change position quickly, and a shorter pulse width allows for more accurate determination of their distance and speed.

The shorter pulse increases the system's ability to distinguish between closely spaced targets and to resolve their positions more precisely. This is particularly important in scenarios where targets are moving rapidly, as it reduces the likelihood of signal overlap and improves overall tracking performance.

In contrast, longer pulse widths could lead to ambiguity in the detection of fast-moving targets, resulting in less effective tracking and measurement. Utilizing a short pulse width thus directly enhances the RADAR system's effectiveness in capturing fast dynamics and provides clearer, more reliable data for interpretation.
