Which frequency bands are commonly used in Pulse Radar systems?

The correct choice identifies frequency bands that are widely utilized in Pulse Radar systems. S-band, C-band, and X-band frequencies are particularly effective for radar applications due to their balance of range and resolution.

S-band frequencies, which typically range from 2 to 4 GHz, are used for long-range detection and have suitable propagation characteristics for various environmental conditions. They are often employed in weather radar systems and air traffic control.

C-band frequencies, around 4 to 8 GHz, offer a good balance between range and resolution, making them beneficial for various radar applications, including surveillance and reconnaissance. C-band systems can detect smaller objects than S-band due to their higher frequency.

X-band frequencies, ranging from 8 to 12 GHz, provide high resolution and are particularly suitable for applications that require detailed target discrimination. This band is commonly utilized in marine radar and military applications.

The other frequency bands included in the other choices, such as UHF, VHF, EHF, and various lower frequency bands like HF, LF, and MF, do not typically align with the operational needs of pulse radars in terms of the resolution and range required for most radar systems.
