PhD position - Modelling and optimization of a 3D GPR tomography measurement system for high resolution soil research

Jülich Research Centre (FZJ)

Jülich, Germany

Work group:

ZEA-2 – Systeme der Elektronik

Area of research:

PHD Thesis

Job description:

Your Job:

In view of current global challenges, like climate change and growing world population, the Forschungszentrum Jülich does research on agricultural topics such as the optimization of the crop yield, improvement of soil and water protection and the minimization of the climate impact. Therefore, a detailed knowledge of flow and transport processes in soils as well as the dynamic development of root growth is necessary.A common geophysical non-invasive measurement method for such applications is the ground penetrating radar (GPR). Typical GPR systems are working in a frequency range from about 200 to 2000 MHz. The GPR signals are coupled into the soil using antennas on the ground surface. Thereby, characteristic properties of soils, such as the electric and dielectric conductivity, are measured without influencing the soils texture and the processes within the soil. In cooperation with the Agrosphere Institute (IBG-3), we will develop a novel measurement system with many antennas that enables for high resolution 3D tomography measurements of undisturbed soil columns.

Your Profile:

  • MSc degree (or equivalent) in electrical engineering or physics

  • Knowledge of programming and data processing

  • Interest in computer-based simulation and modelling

  • Experience in MATLAB

  • Willingness to teamwork is expected

  • Interest in experimental laboratory and Fieldwork

The goal of this doctoral project is the model based simulation and optimization of a novel GPR measurement system for 3D tomography measurements at soil columns. Later on, this model should also be used for the numerical correction of the measurement data. In parallel to this project, a novel measurement system will be set up such that the results of the model can be verified and applied to real measurements.

Our Offer:

  • Outstanding scientific and technical infrastructure – ideal conditions for successfully completing a doctoral degree
  • Opportunity to work together in a team of highly motivated scientists and technicians
  • Possibility to work on the whole development chain
  • Chance of participating in (international) conferences and project meetings
  • Continuous, professional support by your scientific Supervisor
  • Strongly supported on-the-job training at the start
  • Further development of your personal abilities in connection with a socially balanced work environment
  • A comprehensive further training program, including possible German language course
  • Pay in line with 70 % of pay group 13 of the Collective Agreement for the Public Service (TVöD-Bund)
  • Usually a contract for the duration of 3 years

Forschungszentrum Jülich aims to employ more women in this area and therefore particularly welcomes applications from women.We also welcome applications from disabled persons.
