How does the pulse length effect the resolution?

Pulse length significantly affects resolution in various imaging techniques, such as ultrasound or radar. A shorter pulse length results in higher resolution because it allows for better distinction between closely spaced objects, as the pulse can provide more precise spatial information. Conversely, a longer pulse length can lead to decreased resolution, causing overlapping signals that blur the distinction between adjacent features. Thus, optimizing pulse length is crucial for achieving the desired level of detail in imaging applications.
