When operating a RADAR on the 1.5 mile range setting, what are the recommended pulse width and pulse repetition rate?

• A. 0.1 s PW and 1,500 pps
• B. 0.05 s PW and 2,000 pps
• C. 1 s PW and 500 pps
• D. 0.2 s PW and 1,800 pps

Answer: (B)

For radar systems, especially when operating at specific range settings like the 1.5 mile range, the pulse width (PW) and pulse repetition rate (PRR) are crucial for effective target detection and ranging. The pulse width determines how long the pulse is transmitted, and at a 1.5 mile range, a shorter pulse width is typically needed because it allows the radar to effectively resolve targets that may be close together. A pulse width of 0.05 seconds is sufficiently short to ensure that multiple targets can be detected without introducing ambiguity from overlapping echoes. The pulse repetition rate also plays a vital role in determining the maximum range of the radar system. A higher pulse repetition rate, such as 2,000 pulses per second, allows the radar to send out more pulses in a given time frame, improving the system's ability to detect moving targets and providing better resolution at closer ranges. In this case, both the selected pulse width of 0.05 seconds and the pulse repetition rate of 2,000 pulses per second are matched to the operational characteristics needed for effectively detecting and resolving targets at a 1.5 mile range. This combination enhances the radar's performance for close-range operations, enabling it to maintain accuracy and quick response
