With this tool, you can precisely convert a cartesian detector to a polar detector. CartToPolarDetector does not rely on any approximation methods like the nearest-neighbor method or interpolation.

Abstract: The registration of the ISAR (Inverse Synthetic Aperture Radar) signal in a two-dimensional (2D) polar grid and its interpolation to Cartesian coordinates is a problem while for image ...

Helmholtz equation has attracted much attention in many fields such as electromagnetic cavity scattering problems [1] , wave propagation [2] and acoustic problems [3] . Many methods have been proposed ...
