Question:
Which of the following RADAR cannot be used for range measurement?
Which of the following RADAR cannot be used for range measurement?
Show Hint
CW radar measures velocity, not range.
Updated On: Jul 2, 2026
- Pulsed
- MTI
- CW
- FM-CW
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Radar measures range using time delay of reflected signals.
Step 1: Pulsed radar Measures time delay → gives range.
Step 2: FM-CW radar Uses frequency difference → gives range.
Step 3: MTI radar Measures moving targets and can infer range.
Step 4: CW radar Continuous wave has no time reference.
Step 5: Conclusion CW radar cannot measure range. \[ \boxed{\text{CW radar}} \]
Final Answer: \[ \boxed{(C)} \]
