E)echographic.

Question

Quizplus · Accepted Answer

An active imaging system uses its own energy source to emit radiation or pulses of energy, which are directed towards the Earth's surface. The energy reflects back and is recorded by the sensor, creating an image. Passive imaging systems, on the other hand, rely on natural sources of energy, like sunlight, to reflect off the Earth's surface and be recorded by the sensor. Therefore, since the satellite imaging system in question uses its own energy source, it is an active system.
