Question 8-3A3
Element 8 (RADAR)An S-band RADAR operates in which frequency band?
Explanation
The S-band is a standardized frequency range primarily used for radar and microwave applications. According to common international and historical IEEE designations, the S-band operates within the 2 to 4 GHz frequency spectrum. This band is utilized for various radar systems, including air traffic control, weather forecasting, and some maritime applications, benefiting from its balance of resolution and atmospheric penetration characteristics.
Option A (1-2 GHz) describes the L-band, while Option B (4-8 GHz) corresponds to the C-band. Option C (8-12 GHz) represents the X-band. Therefore, only Option D accurately identifies the S-band.
