A wave-based sensor system includes at least one transmitter unit configured to emit waves. The wave-based sensor system further includes at least one receiver unit configured to receive waves and to generate at least one sensor signal corresponding to the received waves. The wave-based sensor system further includes at least one interference detection unit configured to detect interfering waves and to generate at least one interference sensor signal corresponding to the detected interfering waves. The wave-based sensor system further includes a signal processing circuit connected with the at least one receiver unit and the at least one interference detection unit. The signal processing circuit is configured to correct the at least one sensor signal based on the at least one interference sensor signal, thereby obtaining at least one corrected sensor signal. Further, a sensor signal correction method of correcting at least one sensor signal is described.

A multiple input multiple output imaging array for incident angle resolved images with respect to a device under test is provided. The multiple input multiple output imaging array comprises a redundant array of transmit and receive antennas and a controller. In this context, the controller is configured to implement a selection scheme, wherein the selection scheme selects the respective transmit and receive antenna pairs used to create the corresponding image.

The present disclosure relates to a method for the registration of a 3-dimensional all-round view of a moving human or animal body surface. The method accordingly comprises the steps: determination (A) of a movement velocity of at least one region of the body surface and registration (B) at least of the region of the body surface at a timing point at which the value of the movement velocity of this region falls below a defined threshold value.

A printed-circuit board arrangement electrically connects the at least one transmitter and/or receiver unit with at least one antenna element, whereas the at least one transmitter and/or receiver unit and the at least one antenna element are at least partially integrated into the printed-circuit board arrangement. In this context, the printed-circuit board arrangement includes different printed circuit boards, which are mechanically connected to one another in a rigid manner. A first part of the printed-circuit board arrangement is formed by at least one printed-circuit board, of which the substrate is made from a first material which is suitable for high-frequency, and a second part of the printed-circuit board arrangement is formed by at least one printed-circuit board, of which the substrate is made from a second material different from the first material, which is still sufficiently suitable for a low frequency and/or for a direct-voltage range.
