Abstract: A radar device is disclosed including an input DMA module, at least one processing module, and an output DMA module. The input DMA module is arranged to access a memory and supply data from the memory to the at least one processing module, wherein each of the processing modules is arranged to be enabled or disabled. The at least one processing module that is enabled is arranged to process at least a portion of the data supplied by the input DMA module, and the output DMA module is arranged to store the data that are processed by the at least one processing module that is enabled in the memory. Also, a method for processing data by a radar device is provided.

Abstract: A method for processing a radar signal includes adjusting a processing clock signal, wherein the processing clock signal determines an operation period of a signal processing circuit, wherein the processing clock signal is determined based on a time window, wherein the size of the time window is determined based on the maximum time available for processing a portion of the radar signal and wherein the end of the time window is determined such that it does not occur during an active transmission portion of the radar system.

Abstract: A method for processing radar signals includes emitting a first radar signal via a transmitting antenna of a first radar unit, where the first radar signal is phase modulated using a first code and a first frequency offset is added to at least a portion of the first radar signal, and emitting a second radar signal via a transmitting antenna of a second radar unit, where the second radar signal is phase modulated using a second code. The first code and the second code are orthogonal to each other and the first radar unit and the second radar unit are loosely coupled with each other. The method further includes receiving a combined radar signal via a receiving antenna of the first radar unit, where the combined radar signal comprises a reflections of the first and the second radar signals, and processing the combined radar signal at the first radar unit.
