Publication number: 20240036183Abstract: The invention describes a radar method for the coherent evaluation of radar signals in a radar system, in particular a multistatic radar system, wherein at least one or a plurality of received signals is/are received in several signal channels of an antenna arrangement, and wherein a synthetic received signal of a virtual transmitting and receiving antenna is generated using at least one composition model on the basis of the one or more received signals. The invention further describes a radar system according to claim 9 as well as a use of the radar system according to claim 14.

Publication number: 20230333236Abstract: Estimating the ego-motion of a vehicle, e.g., the self-motion of the vehicle, can be improved by pre-processing data from two or more radars onboard the vehicle using a processor common to the two or more radars. The common processor can pre-process the data using a velocity vector processing technique that can estimate a velocity vector at each point of a predefined number of points, such as arranged in a grid in the field-of-view of radars, with coordinates (X, Y, Z (optional)), where U is the component of the velocity in the X-direction, V is the component of the velocity in the Y-direction, and W is the component of the velocity in the optional Z-direction.Type: ApplicationFiled: January 14, 2021Publication date: October 19, 2023Inventors: Alan Christopher O'Connor, Peter Gulden, Fabian Kirsch, Christoph Mammitzsch, Marcel Hoffmann

Patent number: 11320542Abstract: In a method for determining a position, in particular of a vehicle, a first position determination entity is defined as the active position determination entity. The position determined by the active position determination entity is output as the currently determined position. A further position determination entity is started and determines a position on the basis of the received sensor data. If the further position determination entity has reached a stable status, it is defined as the active position determination entity.Type: GrantFiled: June 14, 2018Date of Patent: May 3, 2022Assignee: ELEKTROBIT AUTOMOTIVE GMBHInventor: Fabian Kirsch

Patent number: 11016169Abstract: A method is described in particular for reducing interference due to phase noise in a radar system, in which in a first noncoherent transceiver unit (NKSE1) a first signal (sigTX1) is generated and transmitted, in particular emitted, via a path (SP), in a further, in particular second noncoherent transceiver unit (NKSE2), a first signal (sigTX2) is generated and transmitted, in particular emitted, via the path (SP), the signals (sigTX1 and sigTX2) are received directly or indirectly in the respective other transceiver unit and are processed further therein as received signals sigRX12 and sigRX21, in the first transceiver unit (NKSE1), a comparison signal (sigC12) is formed from its first signal (sigTX1) and from such a first signal (sigRTX2) received from the further transceiver unit (NKSE2) via the path (SP), and in the further transceiver unit (NKSE2), a further comparison signal (sigC21) is formed from its first signal (sigTX2) and from such a first signal (sigTX1) received from the first transceiver unitType: GrantFiled: January 3, 2017Date of Patent: May 25, 2021Assignee: Symeo GmbHInventors: Martin Vossiek, Michael Gottinger, Fabian Kirsch, Peter Gulden

Patent number: 11002818Abstract: A wave-based method has at least two reference stations (1, 2) transmit signals (s1, s2; s3, s4). The signals are transmitted almost at the same time (S1, S2), are transmitted in the same frequency range, and are separable using a multiplexing method. At least one of the sending reference stations (1, 2), besides transmitting its own signal (s1, s2), also receives at least one signal (s2, s1) sent by another reference station (2, 1) at the same time and determines a time stagger (?1) and/or a phase angle between its own transmission and the reception with high precision. At least one receiving station (7) which at least receives the signals (s1, s2) receives the signals (s3, s4) from at least two of the reference stations (1, 2). A system and stations perform the wave-based method.Type: GrantFiled: October 27, 2016Date of Patent: May 11, 2021Assignee: SYMEO GmbHInventors: Martin Vossiek, Peter Gulden, Fabian Kirsch
