Questions and Answers

What is the impact of increasing the PRF beyond a relatively small value?

  • There will be no impact
  • Observed ranges will be ambiguous (correct)
  • Observed Doppler frequencies will be ambiguous
  • Both observed ranges and Doppler frequencies will be ambiguous
  • Why is the choice of PRF considered a compromise?

  • Increased PRF leads to ambiguous observed ranges
  • Decreased PRF leads to ambiguous observed Doppler frequencies (correct)
  • PRF directly determines detection range
  • PRF has no impact on radar performance
  • What is a key radar design parameter impacting detection range and Doppler velocity?

  • Antenna Size
  • Transmit Power
  • Pulse Repetition Frequency (PRF) (correct)
  • Receiver Sensitivity

    True or false: Unambiguous measurement of detection range and Doppler velocity is independent of the selected value of the PRF.
