Abstract
Aspects of the present disclosure involve a radar system employing dual receive antenna arrays. The radar system may include a transmit antenna array to emit a radar beam toward a selected portion of a field of view, as well as a vertical receive antenna array and a horizontal receive antenna array. Each of the receive antenna arrays may include a plurality of antenna elements grouped into sub-arrays that may be configured to receive scatter signals from the selected portion, such as by way of beamforming. The received scatter signals may be combined within each sub-array to generate combined scatter signals, which may then be digitized. A signal data processor may then digitally process the digitized signals from the first sub-arrays and from the second sub-arrays, and correlate the digitally processed signals to generate detection information for each of a plurality of sub-portions of the selected portion.
