The interaction of the electromagnetic radiation produced by an instrument with a specific wavelength to illuminate a target on the terrain for studying its scattered radiance is called:
The interaction of the electromagnetic radiation produced by an instrument with a specific wavelength to illuminate a target on the terrain for studying its scattered radiance is called:
Show Hint
Remember that 'active' means the sensor provides its own light source.

- \( \text{Passive remote sensing} \)
- \( \text{Active remote sensing} \)
- \( \text{Global positioning system} \)
- \( \text{Neutral remote sensing} \)
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Active remote sensing involves the use of an instrument that emits its own electromagnetic radiation towards a target and then measures the radiation that is scattered or reflected back from the target. This is in contrast to passive remote sensing, which relies on detecting naturally available energy.
