In addition to recovery time, what determines the minimum range of a radar set?

The minimum range of a radar set is primarily determined by the pulse width. The pulse width is the duration of time that a pulse is transmitted. When a radar system sends out a pulse, it begins listening for the echo of that pulse after the pulse width has elapsed. If the pulse is too wide, the radar may not accurately determine any targets that are closer than a certain distance, because it will still be receiving its own transmitted signal rather than returning echoes from nearby objects. This creates a "blind zone" where the radar cannot detect any targets. Therefore, a longer pulse width results in a longer minimum range due to the delay in receiving echoes, while a shorter pulse width allows the radar to detect closer targets with reduced risk of overlap between the outgoing pulse and incoming echo.

Other factors can influence radar operation and performance, but they do not directly determine the minimum range in the same way that pulse width does. Receiver sensitivity, for example, affects how weak a signal the radar can detect but not the timing of when it can detect it. Output power influences the overall range but does not establish the minimum range specifically. Frequency modulation mainly helps in improving resolution and target discrimination, but it does not directly set the minimum range limit. Hence, pulse width
