What is the range in frequencies for EM radiation in the radar bands?

The range in frequencies for electromagnetic (EM) radiation in the radar bands is typically considered to span from 500 MHz to 500 GHz. This range encompasses various radar applications, including weather radar, air traffic control radar, and military radar systems. Radar systems operate at specific frequency bands within this range, such as L-band, S-band, C-band, X-band, Ku-band, and Ka-band, each serving different purposes and providing different capabilities based on their frequency characteristics.

The lower end of the range, around 500 MHz, covers frequencies typically used in long-range surveillance, while the upper end, up to 500 GHz, includes higher frequencies used in applications like millimeter-wave radar, which is effective for very precise measurements and small object detection. This broad frequency range allows radar technology to adapt to various operational needs, frequency-dependent propagation characteristics, and target detection and tracking requirements.

The other options provided do not accurately reflect the range typical for radar bands. For example, a range from 200 MHz to 600 GHz would extend below the commonly accepted lower bound and well beyond the application's typical upper limit. The range of 1 GHz to 2 THz includes frequencies that are too high for most radar applications. Finally, the range of
