In a PRR context, what is a stated effect of increasing frequency?

• A. It reduces the transmitter power.
• B. It can be repositioned more rapidly.
• C. It increases the detection range.
• D. It has no effect on performance.

Answer: (B)

Increasing the pulse repetition rate means more pulses are sent each second, giving you more frequent updates. That higher rate lets the radar refresh its bearing and tracking data faster, so the antenna can be steered or scanned to a new position more quickly. The improvement is about responsiveness and update speed, not about boosting the energy per pulse. Peak transmitter power and energy per pulse aren’t directly increased by PRR, so detection range doesn’t inherently grow from a higher PRR. In fact, raising PRR can reduce the unambiguous range, since the maximum range that can be unambiguously observed is inversely related to PRR.
