EITN90 Radar och fjärranalys, 2018/2019


Radio detection and ranging (radar) is one of the most used sensor systems for automatic surveillance of people, machines, and nature. When put on a platform like an aircraft or a satellite, it is often used to form images of the ground and its properties, called remote sensing.  The aim of this course is to give an overview of typical radar systems and their operational principles, including scattering mechanisms and wave propagation. Each student needs to perform a design of a radar system for a specific application, demonstrating ability to trade different requirements against each other.

Course structure

The course is scheduled with two lectures every week, followed by a workshop where the students get to do some practical work on the theory presented during the lectures. Three of the workshops are extended from two hours to a four hour lab, studying the architecture of a real radar system and its associated data.

In order to pass the course, each student needs to be approved on the labs and present a detailed design of a radar system achieving the goals of a specific application.

Examples of radar applications

Radar can have extremely long range and is less impaired by rain or fog than sensors based on visible or infrared light. Some classical applications are

  • Speed measurements through the Doppler effect, used in automatic door openers and police radar guns.
  • Weather monitoring, see for instance Swedish weather forecast site SMHI.
  • Air traffic control, see www.flygradar.se.
  • Remote sensing of the earth and other planets, see for instance activities at ESA and NASA.
  • Detection and tracking of meteors, see meteorscan.com.
  • Sensors for autonomous vehicles, see article.
  • Gesture recognition, see Google Soli.
  • And many more!
