Why is "Range Resolution" important in Pulse Radar?

"Range Resolution" is crucial in pulse radar because it refers to the radar system's ability to distinguish between two closely spaced targets. This characteristic is determined by the width of the pulse transmitted by the radar. A narrower pulse leads to finer range resolution, allowing the radar to differentiate and identify multiple targets that are located close together in distance.

When the range resolution is high, the radar can effectively detect and measure the position of two objects that might otherwise appear as a single target if the resolution were lower. This ability is particularly important in scenarios such as air traffic control, military applications, and weather monitoring, where accurate target identification is essential for safety and operational effectiveness.

In contrast, the other options diminish in relevance here. While tracking multiple radar systems is significant, it is not directly related to range resolution itself. The frequency of radar pulses and power output pertain more to the fundamental design and capabilities of the radar system rather than the specific function of resolving the distance between targets. Thus, improving detection of closely spaced targets directly ties into the concept of range resolution, making it vital in pulse radar operations.
