Abstract: A method and system for obtaining SAR images with reduced or eliminated surface clutter to detect subsurface targets, the method comprising the following steps: -selecting a first frequency and an incidence angle for the radar signal such that the ratio of surface backscattering to subsurface target backscattering is significantly larger for vertical polarization than for horizontal -obtaining vertically and horizontally polarized SAR images based on the same SAR path exploiting the selected first frequency and viewing angle -weighting and differencing the vertically and horizontally polarized SAR images so that the surface backscattering completely cancels between the two images and only the combination of the target backscattering components remains.

Abstract: The present disclosure relates to a balun suitable for realising a wideband transition in the radio frequency band from an unbalanced transmission line to a balanced transmission line. The balun comprises an input terminal; a two conductor output terminal; and a layered structure comprising a number of conducting layers and dielectric layers alternatingly arranged on top of each other. The layered structure comprises at least one ground plane layer and at least one signal transmission layer. The input terminal has a signal connection point and a screen connecting point. An unbalanced signal path is connected to the signal connection point and the screen connecting point of the input terminal. A balanced signal path is connected to the output terminal and being part of the layered structure. A balun transition region transforms the signal from an unbalanced signal to a balanced signal. The balun transition region comprises a non-conducting gap between the screen of the unbalanced signal and a dummy screen structure. The dummy screen structure is a mirror structure, mirrored in a plane of the gap, of a horizontal portion of the unbalanced signal path before the gap. A central conductor or signal conductor of the unbalanced signal path traverses the gap and enters a volume defined by the dummy screen structure. The screen of the unbalanced signal in the vicinity of the gap forms a first balanced conductor being part of the layered structure and the screen of the dummy screen structure, in vicinity of the gap, forms a second balanced conductor being part of the layered structure.
