What will you be doing?

The radar micro-Doppler signature of an object is determined by parts rotating or moving in addition to the motion of the object as a whole, think for example of a rotating aircraft propeller. Radar micro-Doppler signatures are specific for different classes of objects and can therefore be used for object classification. One example is the characterisation of drones, for instance the number of rotors or the rotation rate of the rotor blades may be determined on the basis of the radar micro-Doppler signature. This type of information provides an indication of the load the drone may be carrying. Another example is the micro-Doppler characterisation of human motion. The way of walking, torso motion and swinging of the arms of a person may indicate whether that person is carrying a heavy item or backpack.

The goal of this assignment is to develop and test innovative micro-Doppler feature extraction and classification methods. One line of investigation may be the development of tangible, physically meaningful features. The robustness and distinctiveness of these features can be tested using for instance a Support Vector Machine classifier. Another line of investigation may be the application of neural networks for classification. This line of investigation includes visualization techniques to gain insight in the actual operation of neural networks by highlighting the activation areas within the radar micro-Doppler signatures. Some representative data sets of walking people and drones are readily available. The work may include conducting new measurements to test your results.

The duration of this internship is at least 3 months.

What do we require of you?

  • You are in the final stages of your degree in artificial intelligence, physics, electrical engineering or a similar degree and you have a track record in the field of signal processing;
  • You have experience in programming in Matlab, you are pragmatic and focused on making things work;
  • Some skill in programming in Python is a plus;
  • Next to technical expertise we value communication skills and a results-driven attitude.

What can you expect of your work situation?

You will perform this assignment in the department of Radar Technology. We are a passionate and creative group of professionals (60 people) dedicated to the specification, development and evaluation of innovative, high-performance MMICs, miniaturised and integrated RF subsystems, antennas and front-ends. The department is at the heart of novel, game-changing radar system and signal processing concepts for the military, space and civil domains.
