Abstract: A method is provided for indoor multipath ghosts recognition for a multiple-input-multiple-output radar with collocated antennas. The method includes the step of generating a two-dimensional Range-Doppler map for N number of consecutive radar data frames. The method further includes the step of applying a temporal clustering algorithm to the N number of consecutive radar data frames. Moreover, the method includes the step of applying a linear pattern extraction algorithm on the two-dimensional Range-Doppler map. In this context, the two-dimensional Range-Doppler map comprises detections from at least one target, at least one first-order ghost, and at least one second-order ghost with respect to one wall reflector.

Abstract: A system includes at least two photovoltaic modules each comprising a respective module area being substantially perpendicular to the thickness of the corresponding photovoltaic module. Each of the at least two module areas comprises at least one of two first sides being substantially perpendicular to the thickness of the corresponding photovoltaic module and/or two second sides being substantially perpendicular to the thickness of the corresponding photovoltaic module. In this context, the at least two module areas are arranged in a substantially parallel manner with respect to each other and are shifted with respect to each other in an extension direction of the system. In addition to this, the at least two module areas are arranged in a staggering or alternating or ascending or descending manner with respect to an extension plane in the extension direction of t
