Question

The maximum range, \( d_{\text{max}} \), of radar is:

• A. Proportional to the cube root of the peak transmitted power
• B. Proportional to the fourth root of the peak transmitted power
• C. Proportional to the square root of the peak transmitted power
• D. Not related to the peak transmitted power at all

Hint:

Radar range is related to the power of transmission, and the maximum range increases with the fourth root of the transmitted power.

Answer 1

The Correct Option is B

Step 1: Understanding radar range equation. The range of a radar is related to the power transmitted by the radar, and the maximum range is proportional to the fourth root of the transmitted power.
Step 2: Conclusion. Thus, the maximum range of radar is proportional to the fourth root of the peak transmitted power.
