During the operations of the ERS missions, three courses were produced that introduced the concept of Synthetic Aperture Radar (SAR) and how the two ERS satellites utilised this instrument.

These courses provide an historical reference to ERS' SAR capabilities and examples of radar images produced from the mission data.

The first course serves as an introduction, while the second and third offer more advanced subjects.

• Radar Course 1
• Radar Course 2
