Hope it will help u

Answer 2

Basic components of remote sensing:

• There are total four basic components of any remote sensing such as energy source or illumination, the target, and interaction with it, recording of energy by the sensors, transmission, processing and reception, Interpretation and analysis.
• The energy source has a passive system and active systems such as Sun and radar respectively through which electromagnetic radiation is generated that reaches the sensors.
