When operating a RADAR on the 48 mile range setting, what are the recommended pulse width and pulse repetition rate?

The selection of a pulse width and pulse repetition rate (PRR) for radar systems is crucial for achieving optimal performance while ensuring that the radar can effectively detect and resolve targets at various ranges. When operating a radar at the 48-mile range setting, the recommended choice, which includes a 1.0 microsecond pulse width and a 500 pulses per second repetition rate, is appropriate.

The pulse width of 1.0 microsecond allows the radar to provide sufficient resolution for targets at that range. A wider pulse can help in maximizing the radar's detection capabilities, as it improves the signal-to-noise ratio, especially when operating over longer distances where signal attenuation occurs. With a pulse repetition rate of 500 pps, the radar can efficiently pulse enough times to gather adequate data on potential targets without experiencing overlap in the returns from successive pulses, which could lead to confusing or inaccurate readings.

Selecting this specific combination of pulse width and PRR ensures that the radar operates effectively within the physical limitations of its range and maintains clarity in target detection. This is particularly important in maritime or aviation applications, where accurate target tracking is critical for safety and navigation.
