Research Area of the Research Group on Radar Imaging Techniques, lead by dra hab. inż. Piotr Samczyński, prof. WUT, specializes in digital signal processing for the creation of two-dimensional (2D) and three-dimensional (3D) radar images using the synthetic aperture technique (SAR – Synthetic Aperture Radar) and the inverse SAR technique (ISAR – Inverse SAR). This research team has developed a number of demonstrators of radar technologies, both active and passive SAR / ISAR, covering a wide spectrum of operating frequencies, from low VHF through the C, X, K and W bands and ending with sub-millimeter bands (THz). Other areas of research also include: signal processing in multi-band active-passive radar systems, recognition of radar signal signatures, radio-targeting of radio-communication and radar emissions, and radio-electronic warfare techniques.

Processing of SAR radar images with particular emphasis on the phenomenon of radar speckle. Research in this area can be conducted in two main directions. The first is the study of the possibility of using selected image processing methods to remove speckle: an analysis of the effectiveness of the existing solutions and a proposal of innovative ones, based on e.g. classic methods of adaptive filtration, morphological filtration, multi-temporal (or, generally: multi-look) filtration, but also methods of machine learning, including convolutional neural networks. The second of the above-mentioned fields is the study of the significance of the phenomenon of radar speckle for the classification of the content of radar images and the development of a methodology allowing to maximize its effectiveness - with the specification of the procedure for dealing with the phenomenon of speckle.

The use of SAR radar images in land use/land cover classification in selected fields, including: topographic objects, built-up areas, farmlands, etc. The analysis of the suitability of selected types of SAR data in terms of e.g. spatial resolution and polarization. Investigation of the possibility of using SAR radar images to conduct geospatial analyzes such as population density, etc.
