What is the recommended pulse width and repetition rate for long-range RADAR operation?

In long-range radar operations, the recommended approach is utilizing a wide pulse width combined with a slow repetition rate. This technique enhances the radar's ability to detect targets at considerable distances. A wider pulse width allows for a stronger interaction with the target, resulting in a clearer return echo, which is crucial for distance measurement. Practically, longer pulses can accumulate more energy, improving the signal-to-noise ratio and facilitating better resolution in distant signal detection.

Additionally, a slower repetition rate is beneficial in long-range operations because it permits sufficient time for the radar signal to travel to the target and back. This is particularly important when working with significant distances, as it ensures that each emitted pulse can adequately reflect off the target before the next pulse is transmitted. The combination of these characteristics allows for efficient long-range detection and improved accuracy in target identification.

Other options do not provide the optimal setup for long-range radar. For instance, narrower pulses combined with a fast repetition rate would lead to potential signal loss, especially at long distances where the returns may not have sufficient time to be processed before the next pulse is sent. Similarly, medium pulse widths with variable repetition rates do not consistently enhance performance for long-range operations, as their unpredictability could lead to missed targets or reduced resolution
