Abstract: The present disclosure generally relates to a multistatic radar system and a method for a spatially resolved detection of an object under test. The multistatic radar system includes an at least two-dimensional multistatic array of antenna elements having an at least partially shared coverage area. At least one data processing circuit is coupled to the array. Analog and/or digital beamforming is performed thereby obtaining at least one image of the object under test at least partially being located within the shared coverage area. Processing the image obtained is used to resolve at least one scattering center of the object under test. A spatially resolved scattering center distribution is determined based on the image obtained.

Abstract: The present application relates to a radar test system for testing a device-under-test (DUT) including an antenna array, wherein the antenna array includes: at least two RX antennas having a different antenna polarization and at least one TX antenna, or at least two TX antennas having a different antenna polarization and at least one RX antenna. The radar test system further includes a selection module configured to select one RX antenna and one TX antenna of the antenna array and to connect the selected RX antenna with the selected TX antenna, wherein the selected RX antenna is configured to receive a radar signal from the DUT, and wherein the selected TX antenna is configured to transmit a response signal to the DUT.

Abstract: A pocket filter comprising a plurality of filter pockets, a frame holding the filter pockets, and at least one clamping strip fixing filter layers of two neighboring filter pockets. A profile of the clamping strip is designed in one piece and has a first section and a second section that are movably connected to one another, a T-shaped locking element is formed on the first section, and the T-shaped locking element has a base and a cross-piece extending substantially perpendicularly to the base. A proximal hook-shaped locking element and a distal hook-shaped locking element are formed on the second section, between which the T-shaped locking element is arranged and which engage behind the cross-piece when the clamping strip is in a locked state in which the filter layers of the two neighboring filter pockets are clamped in the clamping strip.
