Topic: Radar and Navigation
An FM-CW (Frequency Modulated-Continuous Wave) radar is essentially
- A. bistatic
- B. monostatic
- C. can operate either as monostatic or as bistatic
- D. none of the above
Answer: C. can operate either as monostatic or as bistatic
Explanation: An FM-CW radar typically has both a transmitting antenna and a receiving antenna. While it can use separate antennas (making it bistatic), it can also be designed to operate with a single shared antenna (monostatic) using a circulator. Note: The official explanation diagram depicts separate $T_{x}$ and $R_{xr}$ antennas, but the official answer key marks (c), indicating it can operate as either.
