Basic Principles of Radar Backscatter

Basic Principles of Radar Backscatter

Text adapted from

In this course you will get an overview of the most relevant parameters that have an influence on the radar backscatter signal. You will learn what role the configuration of a radar system and the properties of the Earth surface play in the signal that you see in a pixel of a radar image.

After this course you will have a solid understanding of what you see in a radar backscatter image. And you will be able to interpret the backscatter signal.

How is the course structured?

The course consists of four lessons. The course will cover the following topics:

Introduction into the concept of radar backscatter
Influence of sensor system parameters
Influence of geometric parameters on the Earth surface
Influence of dielectric parameters on the Earth surface

In this course, we assume that you have some prior knowledge on radar remote sensing. In particular you should have an understanding of the following basics:

  • What is an active radar system?
  • What is the SAR principle?
  • What are radar bands?

If you do not know these concepts, we highly recommend to take the ‘Echoes in Space’ course first. This course will give you a detailed introduction into the basics of radar remote sensing.
