Patent number: 11899094Abstract: Systems, methods, and circuitries are disclosed for compressing radar data. In one example, a method includes storing radar data in a memory, the radar data being stored in a data cube having a slow-time dimension, a fast-time dimension, and a channel dimension. The data cube is divided into one or more zones. For each zone a number of data matrices is selected based on a compression factor. Sets of data matrices containing the number of data matrices are formed and, for each set of data matrices, for each data matrix, the data vectors are coded to generate a coded data matrix. A coding for data vectors in a data matrix is the same and a coding for different data matrices is different. The coded data matrices are combined to generate a compressed data matrix for the zone and the compressed data matrices for the one or more zones are stored.Type: GrantFiled: January 28, 2022Date of Patent: February 13, 2024Assignee: Infineon Technologies AGInventors: Mayeul Jeannin, Farhan Bin Khalid, Dian Tresna Nugraha, Andre Roger

Publication number: 20230384418Abstract: Systems, methods, and circuitries are provided for calibrating a radar system to compensate for a channel offset. In one example, a method is disclosed for processing radar signals with a radar device. The method includes including receiving respective radar signals from respective virtual receive channels, wherein each virtual receive channel corresponds to a combination of a transmit antenna element and a receive antenna element of an antenna element array. Respective received radar data is generated from the respective radar signals and the radar date is processed to identify one or more stationary objects. Based on the radar data, an estimated radar device motion relative to the one or more stationary objects is determined. A difference between the estimated radar device motion and an expected motion of the radar device is determined and a correction vector is determined based on the difference. The correction vector to is applied to subsequent radar data.Type: ApplicationFiled: May 31, 2022Publication date: November 30, 2023Inventors: Mayeul Jeannin, Maximilian Eschbaumer, Farhan Bin Khalid, Dian Tresna Nugraha, Andre Roger
