Postdoc position in Automatic calibration of microwave sensor-systems

Automatic calibration of microwave sensor-systems is currently a very hot topic in both academia and industry and, if successful, the research can also have a major impact in other areas such as telecommunications. The research project on sensor systems, that is part of the ChaseOn Centre at Chalmers, provides an excellent research environment for explorative work in the area of automatic calibration of microwave sensor-systems. Altogether, this position offers an excellent opportunity for fruitful postdoctoral research work in an exciting and expanding field meanwhile being part of a dynamic and outstanding research environment.

Information about the project
There is an increasingly large demand for sensor systems in society and industry for a broad range of important applications such as medical diagnostics, monitoring of industrial processes and radar technology for autonomous vehicles. As compared to other technologies, microwave sensor-systems provide a relatively new and unexplored measurement modality in some areas with a number of competitive features:
(i) good contrast and sensitivity for important scenarios; (ii) suitable for many harsh environments; and (iii) non-destructive and non-invasive. A microwave sensor system has three main parts: (i) the measurement domain with microwave sensors; (ii) the measurement instruments that generate and record the microwave signals; and (iii) algorithms that allow for reliable and accurate estimation of the quantities of interest.

Many standard and conventional techniques and methods for microwave sensor-systems require more and better hardware to improve the performance of the system, which implies higher costs and larger environmental impact. Given the modern computing power of today, significantly better and more robust functions can be implemented in software, which in turn also generates and leads to completely new applications and possibilities. Some important scientific challenges at present involve (i) the rapid and accurate interpretation of the received signals for complex measurement situations and (ii) how to automatically compensate for measurement errors in the physical system by means of software calibration methods.

The aim of this project is to develop new, powerful and versatile physics-based signal processing algorithms and artificial intelligence (AI) methods for microwave sensor-systems. This work is mainly based on physical modelling, statistical analysis, artificial intelligence (with its sub-field machine learning) and computer implementation. Today, the computational capacity and signal acquisition hardware techniques available have reached a capacity to take the physics-based signal processing and artificial intelligence for microwave sensor-systems to the next level. To perform research within this project, we seek a candidate who wants to work as a postdoc in this exciting and rapidly growing cross-disciplinary field of research.

This postdoc position is a part of the Chalmers Antenna Systems Excellence Centre ‘ChaseOn’, which is a consortium between Chalmers University of Technology and a number of company partners including Saab, Keysight Technologies, UniqueSec, Food Radar Systems and Medfield Diagnostics. The ChaseOn Centre gathers stakeholders to build fundamental knowledge and solid competence of antenna systems to meet future challenges in a wide range of wireless applications.

Information about the research group
The Signal Processing Group conducts research on a broad range of topics related to the physics-based processing of sensor signals, the fusion of data from multiple sources, as well as the automatic learning from big data. The research focuses on both the fundamentals of physics modelling of signals and the fundamentals of signal processing, as well as the applications of the methods to relevant problems. Several research topics are undertaken in collaboration with the industry and the university hospital.

Major responsibilities
Your major responsibility is to pursue your own postdoc work within the ChaseOn Sensor System project. You are expected to develop your own scientific concepts and communicate the results of your research verbally and in writing. Another important aspect involves collaboration within academia and with society at large. The position is meritorious for future research duties within academia as well as industry/the public sector.

Position summary
Full-time temporary employment. The position is limited to a maximum of one year.

Qualifications
To qualify as a postdoc, you must have a PhD-degree in applied physics, electrical engineering, mathematics or similar. For this position, it is an advantage to have a strong background in physics and mathematics.
We believe that you are interested in pursuing theoretical research in an international environment. The position requires sound verbal and written communication skills in English.
