Abstract: An RCS reduction surface for reducing a radar cross section of an object is described. The RCS reduction surface comprises at least one absorber portion, wherein the absorber portion is configured to absorb radar waves. The RCS reduction surface further comprises at least one reflecting portion, wherein the reflecting portion is configured to reflect radar waves. A first plane being associated with a top surface of the absorber portion and a second plane being associated with a top surface of the reflecting portion are spaced from each other by a predefined distance. The predefined distance is configured such that radar waves with a predefined wavelength range that are reflected at the absorber portion and at the surface of the reflecting portion interfere destructively with each other. Further, an RCS reduction member and a radar test system are described.

Abstract: A radar target simulator front end, configured to simulate at least one radar target for testing a radar device under test is provided. The radar target simulator front end comprises at least two antenna units, arranged along a first angle under investigation. The at least two antenna units are configured to be selectively activated and deactivated. Whereby each antenna unit of the at least two antenna units generates a simulated radar target along the first angle under investigation, when activated.

Abstract: A method and device for slurrying a suspension, the device including a mixing container with an inlet opening configured to introduce the suspension into the mixing container, a distributor element having a collecting container and an outlet arm fastened to the collecting container, and a shaft with a longitudinal axis, with the shaft and the distributor element arranged inside the mixing container, and the distributor element rotatable around the shaft. The collecting container has a collecting opening that permits passage of the suspension from the inlet opening into the distributor element, the outlet arm has an outflow opening that lets the suspension leave the distributor element, and the outlet arm permitting the suspension to flow out of the distributor element, with a flow of the suspension causing a torque on the distributor element so that the torque supports a rotation around the shaft.

Abstract: A device for slurrying a suspension and a method for operating such a device are disclosed.
