Patent number: 11936108Abstract: 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.Type: GrantFiled: June 23, 2021Date of Patent: March 19, 2024Assignee: Rohde & Schwarz GmbH & Co.

Patent number: 5292007Abstract: Method of and apparatus for continuous non-destructive testing of bar-shaped specimens formed of iron-containing material of specific quality characteristics, where the bar-shaped specimens, such as pipes, move on a roll table (2) along an elongated path through two testing blocks (8, 9) spaced apart along the path. The testing blocks (8, 9) are mechanically decoupled from one another and are logically linked to an electronic testing installation (10). As a specimen moves through a first testing block (8) a signal is developed indicating the presence or absence of flaws and their location in the specimen. The location is referred to the length of the specimens. The testing blocks (8, 9) are located between a supply station (1) and a sorting station (3) with the roll table (2) extending between the two stations. Based on the signals generated, the specimens are sorted in the sorting station between an accepted tray (4) and a number of rejected trays (5, 6, 7) for reworkable or scrap specimens.Type: GrantFiled: March 11, 1991Date of Patent: March 8, 1994Assignee: Benteler AktiengesellschaftInventors: Gerhard Beer, Georg Kellersohn
