A satellite imaging system that beams electromagnetic energy at the surface and then records the energy that is reflected is classified as a(n) ________ system.
A) active
B) passive
C) photographic
D) holographic

Question

Quizplus · Accepted Answer

An active imaging system emits its own energy, such as radar or lidar systems, while a passive imaging system relies on energy sources from the environment, such as sunlight or thermal radiation. Therefore, since the satellite imaging system emits its own electromagnetic energy and records the reflected energy, it is an active system. B) passive is incorrect as it relies on energy sources from the environment. C) photographic and D) holographic do not accurately describe the mechanism of the satellite imaging system.
