  • Automotive MIMO radar system using efficient difference co-array processor
    Patent number: 11888554
    Abstract: A radar system, apparatus, architecture, and method are provided for generating a difference co-array virtual aperture by using a radar control processing unit to coherently combine virtual array apertures from multiple small aperture radar devices to construct a sparse MIMO virtual array aperture and to construct an extended difference co-array virtual array aperture that is larger than the MIMO virtual array aperture by using an FFT hardware accelerator to perform spectral-domain auto-correlation based processing of the sparse MIMO virtual array aperture to fill in holes in the sparse MIMO virtual array aperture and to suppress spurious sidelobes caused by holes in the sparse MIMO virtual array aperture.

  • CFAR Phased Array Pre-Processing Using Noncoherent and Coherent Integration in Automotive Radar Systems
    Publication number: 20230168367
    Abstract: A vehicle radar system, apparatus and method use a radar control processing unit generate compressed radar data signals, to apply the compressed radar data signals in parallel as a three-dimensional matrix to a coherent integrator (which generates a two-dimensional matrix of coherently integrated image data) and a non-coherent integrator (which generates a two-dimensional matrix of non-coherently integrated image data), and to generate a constant false alarm rate (CFAR) threshold from the two-dimensional matrix of non-coherently integrated image data for application to the two-dimensional matrix of coherently integrated image data to detect one or more targets in the MIMO radar signal returns from sample values from the two-dimensional matrix of coherently integrated image data that exceed the CFAR threshold.
