Patent number: 6657599Abstract: A slot antenna has a feeding waveguide extending in a longitudinal direction for guiding electromagnetic waves, with at least one slot constructed in a broad side of the waveguide for emitting an electromagnetic wave. The slot is surrounded on the exterior side of the waveguide by an arrangement for rotating the polarization direction of the electromagnetic wave emitted by the slot. According to the invention, the slot is constructed in the longitudinal direction of the waveguide and the arrangement surrounding the slot is a rectangular polarizer waveguide. One opening of the polarizing waveguide is connected with the broad side of the waveguide and the other has an aperture via which the wave excited by the slot in the polarizer waveguide is emitted.Type: GrantFiled: May 29, 2002Date of Patent: December 2, 2003Assignee: EADS Deutschland GmbHInventor: Klaus Solbach

Patent number: 6639547Abstract: A system for functional testing in a continuous-wave radar having a transmitter circuit for generating radar transmit signals, a transmit/receive antenna coupled by way of a circulator with the transmitter circuit, and a receiver circuit whose input is coupled with the transmit/receiver antenna by way of the circulator, for processing radar echo signals of a target object received at the transmit/receive antenna. The circulator relays the transmit signals generated by the transmitter circuit to the transmit/receive antenna, and splits off echo signals of the target object received from the transmit/receive antenna to the input of the receiver circuit. An RPC circuit coupled between the output and the input of the receiver circuit suppresses those portions of the transmit signals that are split off from the transmitter circuit and/or reflected from the transmit/receive antenna directly into the receiver circuit.Type: GrantFiled: July 12, 2002Date of Patent: October 28, 2003Assignee: EADS Deutschland GmbHInventor: Klaus Solbach

Patent number: 6404378Abstract: A device for increasing the dynamic range of frequency-modulated continuous-wave radar includes a transmitter, a send/receive antenna, a receiver circuit and a circulator. The circulator relays the transmission signals of the transmitter to the send/receive antenna and sends the echo signals of a target object to the input of the receiver circuit, which generates on the basis of the transmission signals and echo signals an intermediate frequency signal having a differential frequency corresponding to the distance from the target object. A reflected power canceler circuit equipped with a control amplifier is provided between the input and output of the receiver circuit. The frequency response of the control amplifier is selected so that the degree of suppression drops to a predeterminable extent with an increase in differential frequency above the cut-off frequency of the control amplifier.Type: GrantFiled: April 24, 2000Date of Patent: June 11, 2002Assignee: DaimlerChrysler AGInventor: Klaus Solbach
