Method of Adaptative-Array Beamforming with a Multi-Input Multi-Output (MIMO) Automobile Radar

A method of adaptative-array beamforming with a multi-input multi-output (MIMO) automobile radar includes a MIMO radar for transmitting a plurality of initial scanning beams in a radial direction. The plurality of initial scanning beams is transmitted one by one at each direction. Accordingly, the MIMO radar receives a reflected scanning beam, wherein each reflected scanning beam is associated with a corresponding initial scanning beam. The reflected scanning beam is used to detect at least one low-resolution target. Subsequently, the MIMO radar transmits a plurality of initial tracking beams, wherein each initial tracking beams is directed towards a low-resolution target. This results in generation of a corresponding reflected tracking beam for each of the plurality of initial tracking beams. Finally, the MIMO radar detects at least one high-resolution target within each reflected tracking beam.
