In a RADAR system set to a 6 mile range, what pulse width and pulse repetition rate should be utilized?

• A. 1.0 s PW and 500 pps
• B. 0.25 s PW and 1000 pps
• C. 2.0 s PW and 250 pps
• D. 1.5 s PW and 400 pps

Answer: (B)

To understand why the pulse width (PW) and pulse repetition rate (PRR) of 0.25 seconds and 1000 pulses per second (pps) is the correct choice for a RADAR system set to a 6-mile range, it's essential to consider the operational characteristics of RADAR systems. When determining the ideal pulse width, it is important to balance the need for resolution with effective detection. A shorter pulse width allows for better resolution and discrimination of targets, making it possible to distinguish between closely spaced objects. In this case, a pulse width of 0.25 seconds is appropriate for a 6-mile range, as it effectively provides a balance between detecting targets and avoiding ambiguities in the returns from multiple echoes. The pulse repetition rate of 1000 pps complements the pulse width given the range. The PRR defines how often the RADAR transmits pulses, which is critical for ensuring that it can continuously scan for targets over the specified range. A higher PRR, like 1000 pps, enables quick updates of target information and enhances the RADAR's ability to track fast-moving objects. In summary, a pulse width of 0.25 seconds allows for adequate resolution, while a pulse repetition rate of
