5.4. Components of a Passive Remote Sensing System

Try these first

1. 1.

   What serves as the primary source of illumination in passive remote sensing?

   Hint

   Think about the main energy source that illuminates objects on Earth.

2. 2.

   What type of signals do sensors record in a remote sensing system?

   Hint

   Consider what happens when the sun's light hits a surface.

3. 3.

   What is the primary source of illumination in passive remote sensing systems?

   • Stars
   • Moon
   • Sun
   • Artificial Lights

   Hint

   Think about natural sources of light.

4. 4.

   True or False: The atmosphere has no effect on electromagnetic radiation.

   • True
   • False

   Hint

   Recall what happens to light as it travels through the atmosphere.

5. 5.

   You are tasked with analyzing satellite images for an agricultural study. Explain how each component of the passive remote sensing system plays a role in your analysis.

   Hint

   Think of the sequence of how data is collected and processed.

6. 6.

   Consider a scenario where atmospheric pollution is high on a given day. Discuss how this may affect the data gathered by remote sensing systems.

   Hint

   Reflect on how different substances might interact with light.
