Which of the following statements is NOT true?
- A. A high PRF pulse Doppler radar has no ambiguities in Doppler frequency.
- B. A high PRF pulse Doppler radar has no range ambiguities.
- C. A high PRF pulse Doppler radar provides an accurate measurement of target's radial velocity.
- D. An MTI radar has many Doppler ambiguities.
Answer: B. A high PRF pulse Doppler radar has no range ambiguities.
Explanation: A high PRF (Pulse Repetition Frequency) pulse Doppler radar has no ambiguity in Doppler frequency (velocity), but it suffers from severe range ambiguities. Therefore, the statement "A high PRF pulse Doppler radar has no range ambiguities" is not true.
