Name one advantage of X-Band in radar technology.

• A. Longer range
• B. Higher power efficiency
• C. Better Bearing Discrimination
• D. Better target response/accuracy

Answer: (D)

X-band uses a higher frequency, which means a shorter wavelength. With the same antenna size, a shorter wavelength lets the radar form a much narrower beam, improving angular (bearing) resolution. It also supports finer range sampling and more precise Doppler processing, so the system can determine target position and motion more accurately. That combination—better resolution in range and angle—translates directly into better overall target response and tracking accuracy, making this the strongest single advantage.

Longer range is not inherent to X-band because higher frequency often suffers more atmospheric attenuation, reducing maximum range. Higher power efficiency is not guaranteed by the band itself; efficiency depends on the specific hardware. While bearing discrimination can improve with higher frequency, the broader improvement in accuracy from better resolution is the more robust, general advantage.
