Tim:
Can the satellites see through clouds?

Steve:
Are the microwave signals like the microwave in our kitchen?

Uncle Roger:
The microwave in the kitchen is used to cook food. Microwaves can pass through the surface of the food and heat it up.

Similarly, the microwave signals sent by the SAR satellite can pass the clouds and see through them. This makes SAR satellites special. We can get SAR images of the Earth even when there are clouds in the sky. Because SAR satellites do not depend on sunlight, they can produce SAR images day and night.
