Internship | Metasurfaces for Compressive Sensing on Radar Array Antenna Systems
3 dagen geleden

What will you be doing?

In terms of reduction of system complexity and costs, without compromising performances. CS allows working with a reduced number of measurements under the conditions that the sensing results are sparse and the sensing is incoherent.

It has been recently proved at Thales Nederland, that among the different schemes to implement CS, the one where the operation of compression is performed before the signal is processed by the receiving modules, therefore directly at antenna level, can achieve much better performances in terms of Signal to Noise ratio (SNR).

In order to do that, it is necessary to realize a metasurface random phase mask that can add at each array antenna element a random phase and combine the different element contributions into a single signal.

Different combinations with different phase settings would form the set of signals for CS. Metasurfaces have attracted an enormous attention of the scientific community in the last decade, and they have been proved to be a breakthrough technology in several applications.

TNO and TU / e have jointly developed a considerable know-how on the design and application of metasurfaces over a very wide frequency spectrum : from microwaves up to optical frequencies.

The goal of the project is to design metasurfaces for CS in phased arrays and demonstrate the concept with the realization of a hardware demonstrator of a metasurface antenna array.

The student will learn the theory, the techniques and tools for the design of metasurfaces. He will also perform a literature study of the current state-of-the-art of metasurfaces.

Then, after having reached a proper understanding of the CS sensing techniques in radar arrays, the student will perform the design of the required metasurfaces and will combine them with an antenna array, based on the requirements derived in collaboration with the research partners.

A hardware demonstrator will be developed and tested to validate experimentally the theoretical results.

What do we require of you?

  • A very good background in Electromagnetism, Optics and Physics;
  • A predisposition for team working, good spirit of initiative and a proactive attitude;
  • Very good knowledge of spoken and written English.
  • This internship has a minimum duration of 6-9 months and therefore applications for shorter periods will not be considered.

    What can you expect of your work situation?

    The internship will be performed at TNO Delft, Stieltjesweg, in the Optics Department, in cooperation Thales NL. The student will have a daily supervisor and will work in a stimulating environment, interacting with other internship students and PhD students, and also with TNO and Thales NL staff members.

    Regular visits will be performed to the THALES NL premises, in Delft.

    What can TNO offer you?

    You want to work on the precursor of your career; a work placement gives you an opportunity to take a good look at your prospective future employer.

    TNO goes a step further. It’s not just looking that interests us; you and your knowledge are essential to our innovation.

    That’s why we attach a great deal of value to your personal and professional development. You will, of course, be properly supervised during your work placement and be given the scope for you to get the best out of yourself.

    Naturally, we provide suitable work placement compensation.
