What is the typical range for pulse duration (PD) in radar?

The typical range for pulse duration (PD) in radar is indeed between 0.1 to 10 microseconds. This range is particularly relevant for many radar systems, as it allows for a balance between sensitivity and resolution. Short pulse durations enable radar systems to produce high-resolution images of targets, as they minimize the distance over which energy is spread out.

By employing a pulse in the microsecond range, radars can effectively detect smaller objects and improve the quality of the data they gather. Longer pulse durations can lead to lower resolution and may make it more difficult to distinguish between closely spaced targets. This understanding of pulse duration is crucial for designing radar systems for optimum performance across different applications, including meteorology and surveillance.

In contrast, pulse durations falling outside the microsecond range either become too long, reducing resolution ability, or remain uncommon for conventional radar applications.
