🔍 Key Concepts

• Pulse repetition frequency (PRF) and how often the transmitter sends out pulses • Relationship between the antenna sweep/rotation and how often the display is updated • Difference between carrier frequency (microwave frequency) and timing-related parameters (pulse width, duty cycle, PRF)

💭 Think About

• Ask yourself: what parameter directly controls how many times per second the radar sends out a pulse, which then appears as one sweep on the display? • Which choice is a timing/repetition parameter rather than a size or energy parameter of each pulse? • How would changing each option (carrier frequency, pulse width, duty cycle, PRF) affect what you see on the radar screen in terms of how often it refreshes?

✅ Before You Answer

• Identify which option is measured in pulses per second or Hertz as a repetition rate, not as a microwave carrier frequency. • Make sure you can explain in your own words what pulse width changes on the display (range resolution vs sweep frequency). • Confirm which quantity, when increased, would cause more radar sweeps per unit time and thus a higher sweep frequency.
