Modeling and Simulating Radar Imaging Systems for Autonomous Vehicles

Leuven | More than two weeks ago

You will help creating radar images approaching camera and Lidar resolution

The usability of radars as imagers in modern autonomous vehicles has seen a significant increase in the past two decades towards achieving full autonomy. Mainly, millimeter-wave imagers are better than optical imagers when it comes to the all-weather operation capability as well as the ambient-light independence [1]. However, optical imagers come superior to millimeter-wave imagers in terms of angular resolution. The concept of Synthetic Aperture Radar (SAR) [2] can be used in autonomous vehicles to achieve higher angular resolution. This is done by exploiting the motion of the platform on which the Radar is mount.

IMEC has a vast on-going research project on automotive millimeter-wave radars. An initial tool has been developed to assess several imaging methods [3]

In this topic, the student will further develop the existing tool to support advanced SAR configurations, to include compatibility with the radar waveform and include practical non-ideal effects such as platform positioning errors. Then, the student will use the updated tool to explore, analyze, and compare effective approaches for 2D/3D antenna array configuration and processing for autonomous imaging applications [4]. 

Type of work: Modelling, simulation, and Radar signal processing. 

The successful candidate will have the following skills: 

  • Ideally: knowledge of basic radar concepts and SAR imaging methods. Alternately, knowledge of wireless communications (physical layer) and beamforming. 

  • Proficiency with Matlab  

  • Basic signal processing 

 

Type: 

  • Master Thesis internship (6 months) 

  • Preceded by optional summer internship (3 months)
