E)Direct

Question

Quizplus · Accepted Answer

An active satellite imaging system emits its own electromagnetic energy (such as radar) and records the energy that is reflected back, which allows it to create images even in darkness, through clouds, and regardless of solar illumination. A passive system, on the other hand, relies on recording natural energy emissions (such as visible light, infrared radiation, or radio waves) from Earth without emitting its own energy. Photographic and holographic imaging systems are types of passive systems that record natural light emissions, while a direct imaging system is not a commonly used term in satellite imaging.
