Signal Processing
Interferometric SAR processor
My study discusses a mission named TanDEM-X that involves two satellites working together in space to create detailed maps of the Earth's surface. The satellites do this by using a special technology called bistatic interferometry, making them the first of their kind in space to use this method. A unique processor, the Integrated TanDEM-X Processor (ITP), manages the data from these satellites. I was part of the processing team and led the absolute calibration and digital elevation model generation. This processor is essential for the success of future missions, ensuring that the data collected and used is as precise and trustworthy as possible. This new approach is a big step forward in space technology and the creation of 3D maps of the Earth’s surface.

Ocean surface currents estimation
I led the The Doppler Centroid Analysis (DCA) of a large research aimed to measure ocean currents from space with X-band SAR sensors. DCA can be a valuable alternative technique for measuring ocean currents compared to traditional methods, offering a different approach to capturing and analysing essential oceanographic information. This contributes to our broader understanding of ocean dynamics and their impact on global ecosystems and climate.
