Question

In active remote sensing of Earth objects from a satellite-borne sensor, the source of the energy used for sensing, lies at the

• A. \( \text{Satellite} \)
• B. \( \text{Sun} \)
• C. \( \text{Object being sensed on Earth} \)
• D. \( \text{Ground station} \)

Hint:

Active remote sensing systems provide their own energy source for sensing.

Answer 1

The Correct Option is A

In active remote sensing, the sensor on the satellite emits its own energy to illuminate the Earth's surface. Therefore, the source of energy is the satellite.
