Various references have been made to the sun as a source of energy or radiation in remote sensing. The sun provides a very convenient source of energy for remote sensing. The sun's energy is either reflected, as it is for visible wavelengths, or absorbed and then re-emitted, as it is for thermal infrared wavelengths.

Passive Remote Sensing
Passive remote sensing is a system that uses the Sun as a source of electromagnetic energy. It records the naturally radiated and reflected energy from the object. The passive remote sensing system is widely used in various fields such as environmental studies, agriculture, and natural resource management.
How does Passive Remote Sensing Work?
Passive remote sensing works by detecting the natural radiation and reflection of energy from the object. The energy emitted from the Sun is absorbed or reflected by the object, and this energy is recorded by the passive remote sensing system. The passive remote sensing system uses sensors to detect the radiation and reflection of energy from the object. The sensors record the energy in the form of an image or data, which can be used to interpret the information about the object.
Advantages of Passive Remote Sensing
- Passive remote sensing is cost-effective compared to other remote sensing systems.
- It can be used to gather data from a large area in a short amount of time.
- It can be used to gather information about the object without disturbing it.
- It can be used to monitor changes in the object over time.
Applications of Passive Remote Sensing
- Environmental studies: Passive remote sensing can be used to monitor changes in the environment, such as land-use changes, deforestation, and water quality.
- Agriculture: Passive remote sensing can be used to monitor crop health, soil moisture, and vegetation growth.
- Natural resource management: Passive remote sensing can be used to monitor changes in natural resources, such as water resources, forests, and wildlife habitats.
Conclusion
Passive remote sensing is a system that uses the Sun as a source of electromagnetic energy. It records the naturally radiated and reflected energy from the object. The passive remote sensing system is widely used in various fields such as environmental studies, agriculture, and natural resource management. It is cost-effective, can gather data from a large area in a short amount of time, and can be used to monitor changes in the object over time.
