Since its introduction in sonar (1975), the major application of synthetic aperture is in side-scan geometry (bottom imaging and mine detection) where azimuthal compression can only be achieved along the sonar trajectory (1D). More recently (2000), o

In top view 2D scan imaging, Planar Synthetic Aperture Sonar (PSAS) is a processing that takes advantage of the overlap of both ping-to-ping and track to track footprints to improve the imaging resolution in both directions. This is done by consideri

An effective and a novel synthesis route for accessing 2-substituted-pyridopyrimidines is described, starting from (2-amino-pyridin-3-yl)-methanol through the use of Ni-doped TiO2 nanoparticles as a heterogeneous catalyst. This approach involves the
