3 educational resources on Radar fundamentals and Radar imaging technology

by |

As you may have gone through Echoes in Space, our MOOC on Radar remote sensing, you might have gotten a glimpse of the complexity that is Radar technology. ‘Radar is for life’, is one of the mottos here at the Jena Earth Observation School, the home of the EO College. This proverb does not only reffer to the life long use of radar data in myriads of application fields, it also reffers to the life long learning process that is necessary to truly understand what the radar signal can tell us about the surface of our planet.

As we are working on an advanced, more in depth course on understanding radar backscatter, we would like to share some valuable resources with you. All resources present radar technology rather from a engineering standpoint and serve as a priceless insight into the technical details of this facinating technology.

“Radar is for life.”

These resources can be very useful to understand the underlying physics, the foundation of the technology and are crucial references to anybody who wants to gain a understanding radar beyond the mere application and usage of pre-processed data.

3 Radar education resources to check out

This list might be short, but the content is comprehensive and gold. Learn about the technology behind Radar from reowned institutions such as Fraunhofer, MIT and German Aerospace Center.

1. Fraunhofer ‘SAR Tutor’

“»SAR-Tutor« is a training software for the radar image analysis. Basic principles of radar technology and in particular the synthetic aperture radar (SAR) can be learned. Starting from textbook metaphor to various multimedia and hypertext techniques support the learning process. Interactive sketches and animations provide space for exploration of the SAR image underlying properties. This is complemented by an integrated interactive simulator for geometric radar effects. Another key feature of »SAR-Tutor« areexercises . Educationally distributed tasks allow students to check their own learning progress. Image interpretation exercises offer practical examples and automatic positive / negative feedback and improve own assessment of the students learning progress. ” (https://www.iosb.fraunhofer.de)

2. MIT ‘Introduction to Radar Systems’

“This set of 10 lectures, about 11+ hours in duration, was excerpted from a three-day course developed at MIT Lincoln Laboratory to provide an understanding of radar systems concepts and technologies to military officers and DoD civilians involved in radar systems development, acquisition, and related fields.” (https://www.ll.mit.edu)

3. SAR-EDU ‘SAR Imaging’

This is a very important Lesson on the way to understand how a Radar image is detected and how a Radar works!
The module “SAR Imaging” introduces basic vocabulary and the underlying principles of the Radar imaging technology. The operating principle of a Synthetic Aperture Radar (SAR), which is the foundation of space borne Radar remote sensing, is explained in this lesson. Furthermore, the imaging geometry and typical characteristics of Radar images are presented.
