This letter presents an imaging strategy using a Mini-Unmanned Aerial Vehicle (M-UAV) radar system to effectively manage data collected on multiple lines. The strategy, called multilines imaging approach (MIA), utilizes 2-D reconstruction and interpolation to provide a 3-D representation. The effectiveness of MIA is evaluated using real data collected at archaeological sites in Italy.
This letter deals with an imaging strategy able to manage effectively data collected on multiple lines by means of a Mini-Unmanned Aerial Vehicle (M-UAV) radar system operating in Sounder mode. The strategy, named multilines imaging approach (MIA), allows an effective 3-D pseudo-representation of the investigated volume. At the first step, MIA faces the problem of reconstructing 2-D domains (slices) by exploiting data collected on one or more lines. Then, MIA interpolates the 2-D reconstructions to provide the 3-D representation. The imaging of each slice is formulated as a linear inverse scattering problem, which is solved by means of the truncated singular value decomposition (TSVD) regularization scheme. The MIA effectiveness is assessed by processing real data collected at Archeological Park of Paestum and Velia, Paestum, Italy.
